The microstructure evolution kinetics of aluminum alloy B206 during artificial aging has been investigated using non-isothermal calorimetry. A combination of differential-scanning calorimetry (DSC) and tensile tests have been utilized to develop an Avrami model to predict the precipitation kinetics as a function of the thermal processing parameters. The Avrami coefficients, found based on a Kissinger analysis, compare well against those reported in the literature for aluminum-copper alloys. The rapid precipitation kinetics predicted by the Avrami model at temperatures higher than 200°C were assessed through a qualitative comparison against hardness measurement results. In contrast to the continuous hardening observed at 150°C, the material softens with continuing heat treatment at 250°C resulting in an overaged state. This can be attributed to the rapid precipitation kinetics at this temperature, leading to the termination of the precipitation-hardening effects at early stages of artificial aging.

"There are an estimated 50 to 100 million dry metric tonnes of low-grade nickeliferous pyrrhotite tailings in the Sudbury area alone, with an average nickel grade ~0.8% (plus cobalt). Pyrrhotite is a highly reactive sulphide mineral that has the potential to generate acidity; consequently, it is stored in large tailings ponds that require perpetual treatment to avoid the production of acidic drainage. Re-processing this material using bioleaching technologies has the potential to recover valuable metals, while reducing the toxicity, reactivity, and acid generating potential of the remaining residues. CanmetMINING is currently developing a stirred-tank bioleaching process to recovery nickel and cobalt from pyrrhotite-rich tailings. Stirred-tank experiments have been conducted with one tailings sample over a range of pH and temperature conditions, resulting in 80 to 90% and 70 to 80% leaching of nickel and cobalt respectively in 10 days.INTRODUCTION Sulphide tailings may represent a significant financial liability for mining companies as these wastes may produce acidic drainage under some disposal conditions. As a result, the companies must post financial bonds large enough to ensure there are sufficient funds for perpetual management of these wastes. At the same time, there are billions of dollars in metals incorporated into these mining wastes waiting to become valorized. Many sulphide tailings are amendable to bacterial oxidation for metal extraction. Re-processing of tailings using bacterial leaching has the potential to recover valuable metals from waste; and reduce the toxicity, the reactivity, and the acid generating potential of the remaining residue. By reprocessing these wastes there is an opportunity to significantly reduce liabilities and financial assurance bonds, while recovering metal values. There are an estimated 50 to 100 million dry metric tonnes of low-grade nickeliferous pyrrhotite-rich tailings in the Sudbury area alone with an average nickel grade ~0.8% (Peek et al., 2011) plus cobalt and copper. Pyrrhotite is separated from pentlandite concentrates by magnetic separation and flotation. It is already finely ground and has often been segregated from other tailings material, making „mining? relatively inexpensive. This represents roughly (> $100/ton) in contained value, with negligible mining costs. This paper reports on the development of a stirred-tank bioleaching process for recovering nickel and cobalt from pyrrhoitite-rich tailings, which is currently underway at Canmet MINING."

An innovative mixed-chloride process for the separation of iron from lateritic ore is described. The separation of Fe(III) from leach liquor is an important process step for the recovery of nickel and cobalt. The patented process of Process Research ORTECH Inc. uses a lixiviant containing hydrochloric acid (HCl) and magnesium chloride (MgCl2) for the leaching of lateritic ores/concentrates followed by the selective solvent extraction step of Fe(III) over other value metals such as Ni and Co. The use of MgCl2 increases the activity of the hydrogen ion in the lixiviant, which reduces the consumption of HCl in the leaching stage and enhances the formation of HFeCl4-, thereby increasing the solvent extraction efficiency of Fe(III) with ketone. The process produces high purity iron oxide (Fe2O3) and regenerates HCl by the pyrohydrolysis of the FeCl3 rich pregnant strip solution. The developed process flowsheet is in closed loop, economically attractive and environmentally friendly.

The 50,000-ton-per-day Concentrator and Crushing Plant, complete with its related water supply, tailings disposal and concentrate handling systems, was started up in a five-month period, with the entire plant obtaining its design capacity six months after the first mill became operational. Individual mill lines, with their spiral circuits, achieved design capacities within a week after the first treatment of ore through each mill. Construction and start-up proceeded together in many areas of the plant, and considerable organization and cooperation between the Owner, the Engineer and the Contractors permitted a smooth transition from construction to operation. PLANT DESCRIPTION THE Carol Lake Plant of the Iron Ore Company of Canada l1as been well described in various technical magazines. The purpose of this paper is to present a brief outline of the start-up of the con-centration complex. This start-up was accomplished in a period of five months, with the plant producing one million tons of concentrate and achieving its design-rated tonnage less than six months after the first ore was treated.

Summary Records of the past show that the first mineral production in what is now the Province of Manitoba consisted of salt, obtained about the year 1800 by the evaporation of brine. Also at an early time in our history, the Ordovician limestone at St. Andrews Locks, East Selkirk, and other localities was quarried for use as building scone in the construction of forts and fur trading posts. Both salt and building stone are still produced in Manitoba, although not from the original sources. In addition, there is now a substantial production of a variety of other industrial minerals and their products such as lime, crushed stone, gypsum, peat moss, and bentonite. The annual dollar value of production of the industrial mineral industry in Manitoba is today greater than at any time in our past and is derived from a greater variety of products. At the present time, exclusive of the various gravel pits operated by the Provincial Department of Public Works, twenty companies operating thirty-four separate pits, quarries, or mines are producing industrial mineral raw materials in Manitoba. This paper attempts to outline the development of the industry from its start about 1800 to the present, giving general information on the various materials produced. Some suggestions regarding the possibilities of establishing new industries based on other raw materials are given at the end of the paper.

BIM, or Building Information Modeling, is transforming the way metallurgical facilities are built, operated and maintained. BIM provides a digital representation of the facility, complete with all physical and functional characteristics - enabling collaborative planning, concurrent design, construction simulation, sustainable operations and predictive maintenance through a connected information model. Building on experience gained in other industries, Hatch is aggressively applying the BIM process to the mining & minerals processing industry to address inefficiencies inherent in traditional document-based information management. Intelligent 3D models support real-time quantity forecasting and cost trending by commodity type and construction work package. By linking procurement and schedule data, material availability and constructability reviews are visualized to verify construction critical path, ensure work front safety and minimize craft downtime. The BIM digital information model connects engineering, construction, commissioning and vendor data, aiding timely asset-centric handover to plant operating and maintenance systems.

In the world of large scale open pit mining, the majority of a mines operating cost is tied to the removal and transportation of the overburden waste material. Typically, many large haul trucks are employed to transport this overburden from each excavating face. The trucks transfer the waste material from deep within the pit to waste dumps on the surface incurring significant costs in operators, road construction and maintenance, vehicle maintenance staff and support facilities, fuel, tires, and spare parts, as well as the capital cost of the truck fleet itself. In addition, the haulage of the actual mined material carries similar operational costs. In both cases, these costs grow as the mine face advances and pit haulage distances increase. Reducing truck haulage is one key to the success of the Dual Truck Mobile Sizer (DTMS). Being the world?s first fully mobile truck dump station, transportation costs can be significantly reduced as the mine face advances. Furthermore, when used in conjunction with a shiftable face conveyor and a mobile overland hopper, substantial cost savings can be achieved. The mobility of the system allows for the considerable reduction in the haul truck fleet. Overall mine site emissions levels are greatly reduced by the fleet elimination, as well as keeping the majority of the hauls on a flat grade within the pit. Emission levels on a typical truck will dramatically spike as the angle and the length of the haul are increased. Moreover, comparing diesel engines versus electric powered conveyors to move the material contributes to the realized savings.

"Electrical disintegration (ED) has been well known as a good comminution method to improve liberation of compositional phases because it was reported that electron avalanche could occur preferentially at phase boundary. But the detailed mechanism of the ED has been still not known. This paper describes the results of ED experiments using synthetic binary sample, copper/resin, under the conditions of various distance between electrodes, and discusses the energy distribution in the three kinds of phenomena in the ED process, which are(1) streamer progression in water, (2) electron avalanche in water, and (3) electron avalanche in solid sample, by measuring current and voltage with elapsed time. Then, it has been found that the energy distribution in the phenomenon (1) is quite low and that the distribution in the phenomenon(2) had a considerably large compared with that in the(3), which indicates that the shockwave generated in water could contribute much to the sample breakage.INTRODUCTIONElectrical disintegration (ED) has been well known as a specific comminution technology which enhanced selective breakage at phase boundary and lead to a good liberation among compositional phases1-6),but the detailed mechanism has not been clarified yet. This study describes energy distribution among the phenomena in the ED process by using a synthetic binary sample, copper/resin, the phenomena of which are (1) streamer progression in water, (2) electron avalanche and shockwave generation in water and (3) electron avalanche in solid sample usually at phase boundary. The energy distribution could be calculated from ED experiments and from voltage-current changes between electrodes as a function of elapsed time.SAMPLE AND EXPERIMENTALSampleThe sample used in this paper was a synthetic binary solid of copper/resin as shown in Figure1.Cut and polished pure copper lump was put into silicone mold and melted epoxy resin was poured into it and cooled, then, finally the binary sample was polished and molded in the form of 10 mm * 10 mm * 10 mm."

"A model based control strategy was implemented at Loulo Gold Mine in Mali, to stabilise the thickener underflow stream density. This stream acts as the feed to the leaching circuit. pH control of the leaching circuit was integrated with the model-based controller due to slow process dynamics that are not suited to PID control. The controller performance was quantified over a period of 6 months, and was compared to the performance before implementation. The model based controller reduced process variability for both thickener underflow density and pH considerably, and resulted in a reduction in flocculant and lime consumption of 9.32 and 6.55%, respectively. INTRODUCTION Reagent consumption in gold processing plants significantly contributes to the total operational costs. In a typical Carbon-in-pulp (CIP) circuit, the reagent consumption associated with leaching, adsorption, elution and regeneration contribute to approximately 15% of the total operational costs (Stange, 1999). At Loulo Gold Mine, the reagent consumption associated with leaching, adsorption, elution and regeneration contributes to 6% of the total operational costs. As such, a reduction in reagent consumption will present a significant opportunity for savings on operating expenditure. Variability in feed ore characteristics results in continuous changes in steady state operating regions, which presents process control challenges as a result of the long residence times in some of the process units associated with gold processing plants. Overdosing often occurs in the presence of process variability to ensure safe operation and to maintain recovery targets. As a means of reducing reagent consumption and accounting for significant changes in the feed to gold plants, some of the plants have resorted to improving their process control strategies around their circuits. This paper focuses on the implementation of a model predictive based controller at Loulo Gold Mine on their thickener and Carbon-in-leach (CIL) tank to: •,stabilise the thickener underflow density, and •,the CIL tank pH."

"The high copper demand as well as the lack of new high-grade deposits, are pushing the copper industry to process low-grade and refractory ores containing chalcopyrite. However, for a quantitative dissolution of copper from the chalcopyrite, the leaching performances still need to be improved. In the present research, we studied and optimized the iodide-assisted leaching of chalcopyrite in H2SO4-Fe2(SO4)3 media. The evolution of surface species during leaching was determined by x-ray photoelectron spectroscopy (XPS) and mineral liberation analysis (MLA). Inductively-coupled plasma spectrometry (ICP-MS) was used to determine the dissolved copper. Significance of experimental results was assessed by statistical analysis while a kinetic analysis of the leaching process was performed by fitting the experimental data with the Shrinking-core model. Results showed the significant positive effect of iodide on copper extraction rate. In the presence of KI, the dissolution rate of copper was almost double than in the parallel experiments without KI. Whether using KI or not, elemental sulfur was generated on the surface of the leached chalcopyrite. Nevertheless, in the presence of KI, the passivation layer did not arrest the leaching. Analysis revealed that the leaching rate was limited by the chemical reaction control step.INTRODUCTION Due to the large demand of copper, processing low-grade ores containing copper sulfides such as chalcopyrite (CuFeS2) has become unavoidable (Watling, 2013). Since ores with CuFeS2 may also contain appreciable amounts of arsenic that cannot be smelted, and because low-grade ores are uneconomic to smelt, the hydrometallurgical technologies are crucial for recovering the copper (Dutrizac, 1978). Sulfate-based processes are attractive because of the lower operating costs and because the sulfate ion is more suitable in case copper would be recovered via electrowinning. In ferric sulfate solution, chalcopyrite undergoes oxidation due to the large amount of Fe(III) and dissolution due to the presence of the sulfate ion (Majima, et al., 1985). The leaching reaction in ferric sulfate medium can be represented as in (1):"

The effect of interrupted quenching (IQ) treatments on natural aging and bake hardening response of Al-Mg-Si alloy was investigated by hardness measurements, tensile test, differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). The results show that interrupted quenching at 100oC could effectively suppress natural aging and improve bake hardening response. The optimized interrupted quenching treatment is 100oC for 45min, which gives the alloy a relatively low T4 temper strength and higher bake hardening response. The formation of highly dense cluster(2) during the interrupted quenching could be the reason for suppressing the natural aging and accelerating the precipitation of ß? phase during the paint bake treatment. In addition, interrupted quenching at higher temperature (170oC) results in unfavorable properties in both T4 temper and paint bake treatment. The formation of large precipitates is responsible for these undesired effects.

The general recycling process of tungsten scrap to produce tungsten raw materials (tungstic acid, ammonium paratungstate (APT) and WO3) have been carried out by the oxidation, milling, sodium-fusion, dissolution, and extraction processes. Many studies on the high temperature oxidation of tungsten scrap have investigated various aspects such as swelling kinetics, fracture resistance, and the effect of alloying composition. However, the accelerating factors on the scrap oxidation rate during oxidation were not considered here. In general, oxidized products were fused with sodium carbonate or sodium hydroxide to produce Na2WO4. Later in the process, solid Na2WO4 was dissolved in water. This process required considerable reaction time and was a costly process. Therefore, the aim of this study was to increase the solubility of solid oxidized products to produce Na2WO4 solution by hydrothermal reflux method. Na2WO4 solution was used to produce CaWO4 and H2WO4 by general chemical reactions with calcium chloride and hydrochloric acid. Ammonia solution was also added to the tungstic acid to produce APT. In this study, the effect of ammonia addition on the APT precipitation process was investigated in detail.

"Buried pipelines, tanks and other similar equipment are almost always present on large scale industrial sites, including in the oil and gas fields. However, as the proverb “out of sight, out of mind” suggests, it is easy to overlook proper maintenance procedures and simply assume that corrosion protection measures in place are working correctly. Unfortunately, this is not always the case, leading to significant environmental damage and loss of production. This paper describes several cases from various industries where buried equipment failed because of corrosion, sometimes with catastrophic results. It also presents various strategies, based on experience and new research, to help predict and prevent damage to underground metallic structures.INTRODUCTION Metallic underground structures are extremely common in industrial and commercial settings for numerous reasons. Burying pipes, tanks, wires and other similar equipment has numerous advantages: it provides significant protection from mechanical damage, frees up ground space that can be used for other purposes, requires little to no support structure and is generally more esthetically pleasing. However, this last benefit can also be considered the most significant disadvantage of underground equipment: becoming invisible and forgotten. While every engineer is aware of the importance of preventive maintenance, it is also human nature to somewhat forget about equipment that is hard to inspect and assume that everything is fine. This is unfortunately not always the case and failures in industrial settings can have extremely serious consequences. While economic aspects immediately come to mind (loss of production, cleanup cost, etc.), failure of underground equipment also results in an environmental and therefore public relations nightmare, especially in the oil and gas field. Leaks that would have been considered negligible in the past can now make national headlines and perfect reliability, while probably impossible to achieve, is now the goal of most companies. While environmental damage (real or perceived) is most often associated with leaks in the oil and gas industry, it can also affect the mining world. For example, the authors have worked on a project where a buried slurry pipeline had ruptured in the ground, causing a release of perfectly inert tailings. While the economic loss was low, the leak was reported in local media and caused a public relations problem."

The mining industry represents a significant investment in infrastructure of which steel plays a key role. Many structures in a mine are made of steel including shaft structures (buntons, station steelwork and headgear); stope structures (roof supports, pipe hangers); haulageway structures (ore transfer stations, electrical stubbies); and surface structures (plant buildings, tank supports, pipe gantries, conveyor belts, stacks, stockpile structures, stairways and railings). Maintenance of structural components can often be difficult because of the environment, including those where corrosive fumes persist, or limited access, such as in shafts where access is limited, or to short maintenance shifts or where limited working space is available. Thus a cost-efficient, long-lasting and maintenance-free protection system for steel should be specified. Galvanizing provides the required high-quality, long-term corrosion protection to steel. Galvanizing provides protection in two ways, first as a physical barrier to corrosion and secondly by means of cathodic or sacrificial protection that is unique to zinc. The dual nature of corrosion protection provided by galvanizing significantly extends the service life of steel even in the most challenging environments. The unique corrosion protection properties provided by galvanized steel will be highlighted with global mining application case studies.

"Hydrogen induced failure and degradation in structural metals, namely hydrogen embrittlement, has been a long-standing industrial problem for more than one century and remains unsolved. Despite the proposal of numerous models, no consensus has been reached, and considerable discrepancies in experimental observations and theoretical calculations exist. One aspect that is central to the understanding of hydrogen embrittlement is the interaction between hydrogen and grain boundaries. In this study, we investigated the influence of several solute elements (i.e., Cr, Mo and Nb) on hydrogen segregation at the representative 9 grain boundary using first-principles calculations. Our results showed that the presence of Mo and Nb can reduce the tendency of hydrogen segregation at grain boundaries, while meanwhile enhance the grain boundary strength. This indicates that Mo and Nb are salutary elements that can be used to increase the material’s resistance to hydrogen embrittlement, providing new insights in designing hydrogen embrittlement resistant Ni alloys. INTRODUCTION Hydrogen embrittlement (HE), a phenomenon of hydrogen triggering premature failures in structural metals, has been a headache for industries ever since its first discovery one century ago (Johnson, 1874; Zhou, Marchand, McDowell, Zhu, & Song, 2016; Zhou, Ouyang, Curtin, & Song, 2016). It is well accepted that the segregation of hydrogen at microstructures such as grain boundaries (GBs) plays a key role in determining the occurrence and severity of HE. GBs are two-dimensional defects where significant local lattice distortion exist, which leads to large free volume and thus locations for hydrogen trapping and segregation. Numerous works have clarified GBs as the energetically preferable places for hydrogen segregation. For instance, Geng et al. demonstrated the preferential segregation of hydrogen at the S5(120) GB in several metals, and suggested a decohesion-type of HE in light of Rice-Wang thermodynamic theory (Geng, Freeman, & Olson, 2001). Birnbaum et al. illustrated that complete intergranular crack of Ni GBs can be induced by hydrogen segregation when the hydrogen concentration is sufficiently high, evidencing the significant role of hydrogen accumulation on GB weakening (Lassila & Birnbaum, 1987). Yamaguchi et al. demonstrated strong segregation hydrogen also occurs at S3 GBs in alpha-iron, showing that local hydrogen clustering (i.e., multiple hydrogen atoms, up to six, per unit cell) can be trapped at the S3 GB (Yamaguchi, Kameda, Ebihara, Itakura, & Kaburaki, 2012)."

In the this study, surface segregation of Mg and Ca with Mg addition range from 5 to 10wt% in Al-Mg alloys with Mg+Al2Ca master alloy and its effect on the oxidation resistance were investigated. The addition of Mg+Al2Ca master alloy as the Mg alloying element led to the surface enrichment of Mg and Ca during high temperature oxidation. As a result of the oxidation test by TGA, the oxidation resistance of all the examined alloys was significantly improved with increasing Al2Ca content. The weight change of Al2Ca added Al-5Mg and Al-7.5Mg alloys indicated the complete oxidation resistance during the whole oxidation test time, while a slight weight increase was shown in the case of Al-Mg alloys even with Al2Ca addition. The improvement of the oxidation resistance in Al2Ca added alloys may be attributed to the formation of the protective oxide layer mixed with CaO and MgO on the surface.

Product Lifecycle Management (PLM) solutions have been serving as the basis for collaborative product definition, manufacturing, and service management in many industries. They capture and provide access to product and process information and preserve integrity of information throughout the lifecycle of a product. Efficient growth in the role of Building Information Modeling (BIM) can benefit vastly from unifying solutions to acquire, manage and make use of information and processes from various project and enterprise level systems, selectively adapting functionality from PLM systems. However, there are important differences between PLM?s target industries and the Architecture, Engineering, and Construction (AEC) industry characteristics that require modification and tailoring of some aspects of current PLM technology. In this study we examine the fundamental PLM functionalities that create synergy with the BIM-enabled AEC industry. We propose a conceptual model for the information flow and integration between BIM and PLM systems. Finally, we explore the differences between the AEC industry and traditional scope of service for PLM solutions.
