Au/TiO2 catalysts were prepared by deposition-precipitation using NaOH (DPN) (~3 wt % Au) and urea (DPU) (~8 wt % Au), and calcined at various temperatures between 100 and 400 °C. They were characterized by UV-Visible, XANES, EXAFS and TEM. Their activity were tested in the reaction of CO oxidation at 5°C. After preparation, the gold species are in the oxidic state III. They begin to transform into metallic gold under air at ~100 °C for DPN and ~150 °C for DPU. At 200 °C, all the gold is metallic for the two preparation methods. The particle size increases from 1.5 to 3.5 nm with the calcination temperature. The catalytic activity for CO oxidation increases with the percentage of metallic gold, and it is maximum at 200°C for both types of samples. The activities (per mole of Au) are the same for the two types of catalysts. At higher temperatures, the catalytic activity drops. The decrease of activity is mainly due to a change of particle shape with the calcination temperature rather than to the increase of the particle size. At a calcination temperature of 200°C, the particles present small facets with rounded parts, and their outer surface contains a large proportion of low coordinated sites (steps and corners) while at high temperature of calcination, they are truncated octahedra with smooth facets.

"The Canadian tax treatment of mining operations outside Canada is not as attractive as the treatment of Canadian operations. Further, the Canadian company that invests abroad a host of complex rules. This month, Tax Notes examines some of the major Canadian tax considerations confronting the Canadian company that wants to invest abroad. IntroductionCanadian-based mining companies are investing abroad more than ever before. These foreign investments trigger a complex set of tax rules that are distinct from the rules that apply to Canadian investments. In most cases, careful tax planning is mandatory if the company's tax liabilities are to be minimized. This article summarizes the main tax considerations that need to be taken into account with respect to a mining investment outside Canada.Branch Versus SubsidiaryOne of the first questions that arises in connection with a prospective foreign investment is ""Should we invest directly (that is, in a branch operation), or should we invest through a foreign subsidiary?"". In the case of a branch operation, the Canadian company owns and operates the business directly - that is, the foreign business assets are part of the Canadian legal entity. In the case of a foreign subsidiary, the foreign business operation is owned and managed by that subsidiary. The tax treatment of a branch and a subsidiary can be quite different."

The effect of porosity on mechanical behavior of rock has been studied in the past using both experimental and numerical techniques. One important aspect of this study that has not received much attention is the role of void size and distribution on the mechanical behavior of rock. In this study, the CA2 computer program that is a hybrid discrete-finite element program for two-dimensional simulation of geomaterials is used. Numerical specimens with different macro-void sizes are loaded uniaxially. The Young?s modulus, Poisson?s ratio, uniaxial strength and crack initiation stress are studied. The numerical results are compared with the database of experimental tests on Plaster of Paris specimens containing Styrofoam spheres with different void sizes and porosities. It is shown that the macro void spatial distribution is partly responsible for the scatter of the experimental data. It is also shown that not-only the porosity but also the pore size can affect the deformability, crack initiation stress and rock strength.

"The virtue of spray drying is that it is a drying method, and so far the only one by which it is possible in one operation to divide a mineral concentrate into its basic primary particles.,In so doing, each particle gets the same treatment and the result is a dry concentrate more homogeneous than any other known concentrate drying process. This is particularly good for a flash furnace requiring a bone dry finely divided feed. The spray dryer also features a very short residence time and due to the very quick operation the solids are kept cool thus preventing any risk of fire or explosions on these pyrophoric materials.There are many spray dryers now in operation in the mining industry and one of the latest applications is in South Africa where a spray dryer is treating a copper-nickel platinum concentrate which is, after drying, fed toan electric arc furnace. Experience has shown that the concentrate should contain 4% moisture for the furnace, and this is achieved by drying the concentrate bone dry and then back-mixing with thickener underflow pulp to provide an extremely homogeneous feed to the smelter. As mentioned before, mixing with pulp would be more of an advantage because we would not be evaporating water which would have to be added again afterwards.One of the first spray dryers to go in was at Western Mining Corporation in Kambalda in Western Australia. (A series of slides was then shown)."

Comminution is the science of size reduction of brittle materials. It is integral to mineral extraction and is one of the most energy intensive processes in the mining industry. There are a number of tests used to quantify the strength of ore, which are then used to size the AG / SAG mill in circuit design. The calculated energy utilized for breakage in these devices is based on the assumptions that the materials treated are of average shape and that the processing equipment is designed to break the ore as efficiently as possible under the given operating conditions. In drop weight tests, it was found that shape significantly influences the measured rock strength. Controlled experiments with variations in blends of rock shape show that mill throughput increases with the addition of weaker shaped rocks.

"When Texas Gulf Sulphur Company discovered the Kidd Creek ore body in 1964, a crash program began almost immediately for the design and construction of a modern concentrator. It was necessary to mill two distinct ore types; one containing copper and zinc, the other lead, silver and zinc minerals. The final concentrator design was to handle 9,000 tons of ore daily in three circuits. One circuit was to treat copper-zinc and another lead-zinc ore exclusively on a permanent basis. A central circuit was designed with adequate flexibility to treat either of the above ore types in accordance with planned mining schedules. Ecstall Mining Limited, a wholly owned subsidiary, now operates the mine and concentrator complexes for Texas Gulf. The mine is located 15 miles north of Timmins and the concentrator 15 miles to the north-east along Highway 101. The ore is hauled from the mine to the concentrator over a 17-mile railroad. Initial milling operations began in November, 1966.1 - ABSTRACTThis paper deals with bulk reagent handling at the Kidd Creek concentrator. The reagent section at Kidd Creek has operated excellently since milling began in 1966. The bulk handling techniques are satisfactory. They have contributed substantially to good working conditions, economical practices and metallurgical efficiencies. The bulk handling features described should be considered in existing and proposed concentrators."

"Applying DEM to prediction of tumbling mill performance is challenging because several different modes of breakage are active in the process. As our knowledge of breakage and computational capacity improve, it is worth revisiting previous simulation tasks which did not produce a satisfactorily realistic description of a measured process. At SAG 2006, we reported the simulated and measured outcomes of treating a well characterised ore in a 1.2 m diameter mill. This well instrumented, pilot scale mill at the University of KwaZulu-Natal has been combined with some new approaches to ore testing to allow different modes of breakage to be tested. The mill design allows the rate of generation of fine material to be measured in close to real time for autogenous and SAG mill charges. The updated simulation model estimates mass loss with particle evolution and embeds the cumulative damage and breakage.The simulated results are compared with the measured results. Issues such as relating modelling inputs to particle breakage characterisation data and the accuracy of the predictions of the models are discussed."

"The title of this paper probably sounds quite simple and self-explanatory. The problem, however, was not a simple one, and proved somewhat baffling and expensive over a period of years. After outlining the problem, and the methods which were used to overcome it, we will present our solution, or perhaps it would be more accurate to say the partial solution which we reached.We have in the cyanide circuit at Upper Canada two Dorr Single Tray Thickeners with 30 ft. diameter wood stave tanks 12 ft 4 1/ 2 in. deep. In the years prior to 1948, when the tonnage was 250 to 280 tons per day, two stage thickening was practised. As the tonnage was increased to 450, 500, and finally 560-600 the thickeners were used in parallel.Some settling problems were encountered, and in those days the means to combat these problems were very few. The only remedy was to dump in pounds and pounds of lime. Then along came a few reagents, and the writer remembers one in particular, - 11 Carboxel11 (carboxymethlycellulose). When water or solution was added to this reagent, the result was a gooey mass somewhat resembling tapioca. One drawback was that it stayed in this state, and didn't go anywhere. A method was finally developed of containing the mass (or mess) on a fine screen, and dissolving some of it was a fine spray of solution. The only thing the writer recalls was that it was not a very effective settling agent.Shortly after this time, along came the new flocculents, first a few, and then many, and our settling problems were over.But when the settling problem was solved at Upper Canada, some other problems were creeping up on us."

"The Riviera tungsten occurrence in the Cape Province of South Africa was discovered in October 1979 as a result of stream-sediment panned concentrate sampling. The Cape age granite and late Precambrian Malmesbury Group carbonates and chlorite schists which it intrudes and which host the mineralization are covered by between 10 m and 30 m of Tertiary/Recent alluvium and clay. The scheelite/powellite and molybdenite mineralization occurs in a greisenized granite cupola with an overprint of porphyry-type alteration as well as in minor skarns. The ore reserve is estimated to be 46 million tonnes at an average grade of 0.216% W03 and 0.020070 Mo. The deposit is uneconomic at current tungsten prices. IntroductionDuring the 19705, Union Carbide Corporation was a major producer, processor and supplier of tungsten and derivative products to end-user manufacturing industries. The corporation owned and operated two tungsten mines in the United States, and one in Brazil, and operated a plant in the United States which produced ammonium paratungstate (APT) which is an intermediate product in the production of tungsten wire and tungsten carbide for cutting tool insets and hard facings. In 1975 the three mines were ageing with short-life reserves and high production costs. The world market for tungsten was buoyant and prices, in constant dollar terms, had risen steadily over the past 15 years (Fig. 1).It was against this background that a decision was made to explore for tungsten in North America, South Mrica, Australia and Brazil."

"In order to obtain the equipment necessary to automate the equipment it was decided that the Department of Mines and Milltronics would jointly survey the circuit. This survey involved a metallurgical study by the Department of Mines and Milltronics took sound recordings during manual operation, checking in circuit bottle necks and determining the number of sensors that could be applied.The conveyer is driven by 2 PIV drives, each has a variable speed of 3/ 1. The cross conveyer that feeds directly into the rod mill feed chute will contain an automatic sampler and will eliminate the necessity of stopping the belt feeders to take samples. At present, hourly samples are taken from this point and the circuit is upset and cycling results.The Adequate scale is very close to the rod mill to totalize and thereby give a continuous indication and the second purpose is to take a signal from it and control the solution addition to the rod mill.A pneumatic positioner was obtained and put on the scale which produces a 3 tp 15 psi signal which is proportional to the actual tonnage going across the scale. This signal was fed to a bias loader which was mounted on the control panel. From there the operator can set the amount of solution that is wanted by the rod mill. No matter what the feed rate is, the signal coming from the bias loader will follow it automatically. This in turn goes to the pneumatic solution valve (1 ½” ) and the solution goes in with the feed to the rod mill. This is only part of the solution required for dilution since the rest of it is used as a force jet for the feed to the rod mill."

Increasing energy costs associated with mining have become an issue that must be addressed by industry to ensure sustainable production. As underground mine ventilation systems account for 40% to 50% of a mine?s total energy requirement, initiatives to maximize their efficiency have been introduced worldwide. A control method known as Ventilation-On-Demand (VOD), which adjusts the ventilation system by responding to the activities of mine personnel and air quality, has been commissioned at Vale?s Coleman Mine. This initiative is an effort to reduce energy consumption, maximize efficiency of the ventilation system while ensuring air quality. There are five control strategies that can be executed with the VOD control system in place at Coleman Mine: Manual real time control Time-of-Day Scheduling Event-based control Environmental control Activity Based Control/Tagging This paper describes the system, control strategies and impact on energy consumption and flexibility of airflow distribution as applied at Vale?s Coleman Mine.

The Halfmile Lake stratiform volcanogenic massive-sulfide deposit consists of pyrrhotiterich breccia-matrix sulfides and pyrite-pyrrhotite-rich layered sulfides that form a laterally continuous sheet stratigraphically underlain by an extensive pyrrhotite-chalcopyrite-quartz stringer zone. Mineralization is hosted by a sequence of felsic pyroclastics and volcanic-derived, fine-grained metasediments. The proportion of volcanic to sedimentary rocks indicates increasing vent proximity from southwest to northeast across the deposit area. Fine- to medium-grained felsic pyroclastics and roughly equal amounts of fine-grained metasediments comprise the stratigraphic footwall to the mineralization. Quartz-feldspar porphyritic bodies cut this sequence and may have provided the heat source for exhalite activity. Felsic tuffs, locally crystal-rich, and lesser amounts of metasedimentary rocks make up the immediate stratigraphic hanging wall. This sequence is stratigraphically overlain and locally interfmgered with mafic volcanics that contain substantial proportions of felsic fragments. Deposition of sulfides post-dated the beginning of felsic volcanism, which places the deposit in the middle of the Lower Tetagouche Group. Compositions of the volcanic rocks range from basalt to rhyolite and exhibit sub-alkaline affinities. Strongly overprinted whole-rock, trace-element, and REE geochemical signatures resulting from mineralizing hydrothermal activity confirm the genetic relationship between the stringer zone and the mineralized sheet. Large-scale D1 folding has overturned the entire sequence. D1 thrust faults and related sheath-like folds have profoundly affected sulfide distribution. D2 is manifested by a penetrative S2 foliation, and D3 is represented by large-scale open folds.

Stirred milling of nickel laterites offers possibilities for improving liberation and selective size reduction of soft nickel-bearing minerals in laterites. Batch grinding tests were performed in a Netzsch LME4 stirred mill on siliceous goethitic (SG), goethitic (G), and saprolitic (SAP) nickel laterite samples (- 2000 ?m particle size) to evaluate the effect of stirrer speed, solid content, water salinity and grinding time. A fine mineral product (-38 µm) was used to evaluate the effect of selective grinding and Ni upgrade. The optimum grinding time for the highest Ni upgrade was 0.25 min, 0.1 min and 0.1 min for the SG, G, and SAP nickel laterite, respectively. A new feed (38-2000 µm) for each nickel laterite sample was prepared for batch grinding tests under the optimum grinding conditions. Upon grinding the 38-2000 µm feed, the - 38 µm product confirmed the effect of selective grinding and nickel upgrade. Size classification followed by stirred milling is a suggested process for Ni upgrade. The best Ni upgrade result was achieved on the SG nickel laterite among the three samples. The Ni grade increased from 0.85% to 1.37%, with 27.8% Ni recovery. Bottle roll leach tests showed that for SG and SAP samples selective grinding had no dramatic effect on Ni extraction due to the slow leach rate of hard mineral particles. Stirred milling of G sample increased the surface area of goethite, resulting in higher Ni extraction. Gravity concentration through a Knelson Concentrator was not effective in the further treatment of the stirred milling products either due to the poor operating conditions or due to the mineralogy characteristics of the feed samples. The energy requirement in the stirred milling was investigated. The first pass of the signature plots study is critical for the purpose of selective grinding, because the best result on selective grinding is achieved in the early stage of the grinding process.

"Predicting the performance of the whole mining process is surely the holy grail of predictive simulation. This can be named ‘Integrated Process Prediction’.The objective is to be able to predict the response of the processing chain, from mining to concentration, to changes in the ore type. This can apply to greenfields design – selecting processing options to optimise the overall mine performance within the constraints and aspirations of the greater community and environment; expansion and optimisation of existing plant to deal with changes in economic drivers and ore types; and on-line control – predictive reaction to ongoing changes in ore processing types in an operation.In order to achieve this there are several broad key components that are required: ore characteristics based on in-situ rock properties; a reliable 3D map of the ore body by the key processing parameters; prediction of how the rock fragments and the energy requirement to break it; the ability to predict and track progressive mineral liberation of the rock through the reduction process; the response of rock to separation processes as a function of the rock mineralogical properties. This requires the identification of primary rock properties and associating them with the rock particles as they move along the mining process chain to a concentrate or various forms of waste.This paper looks at the value of this integrated approach; the challenges it poses; the technology and capability we require; and how as a mineral processing community we can address the challenges."

"Representatives of various industries and the Canadian coast Guard formed a Bulk Cargoes Committee three years ago. In 1976 and 1978, I have attended the meeting which take place once per year here in Ottawa as representative of the Canadian Mineral Processors, Dave Hendricks from Granisle accepted the charge in 1977. Our Secretary, Bob Bruce, has suggested repeatedly that I report to the Membership on the deliberations to this group. Twice I found good excuses; this year I did not. I was reluctant to address you since the Committee's deliberation proceeded at a pace which might be identified as Government squared. The Committee advises a Government agency which in turn negotiates with foreign Government agencies.At the outset, I will describe the developments which led to the formation of the Committee and its purpose.The Canadian Mining Industry ships annually millions of tons of products to overseas customers; be it iron ore, coal, fertilizer, or base metal concentrates. Most loadings are in vessels of foreign registry and all will be directly affected by Canadian or International regulations of the transport of such bulk commodities. The major shipping nations are members of an Intergovernmental Maritime Consultative Organization (IMCO). This organization elaborates regulations which govern shipment of all cargo, bulk materials and concentrates included. At IMCO'S deliberations, Canada has one vote, one voice on the Consultative Committee and is represented by our Coast Guard. The Coast Guard has over the years been in contact with industries when discussions concerned shipment of bulk cargoes. In the early sixties, a ""Concentrate Committee"" did exist. It consisted of metallurgists from a number of mining companies and Government representatives. This committee was instrumental in the development of what became known as the ""Concentrate Code"", legislation which has evolved into the Canadian Bulk Cargoes Code as it is known today. The concepts of the flow moisture point and transportable moisture limit originated from its work. Incidentally, both criteria are widely accepted and utilized world-wide. The Concentrate Committee faded away once the Concentrate Code has been adopted."

?Globalization and the impact on mine operations? is one of the themes of the 2003 annual CIM meeting. Global mining business in practice always means to act with local base material resources in order to reach the mining company?s global business goals. On the other hand these operations are characterized by cost pressure and cycling product prices. Driven by actual prices, local product markets and local production cost, one time one mine can be most efficient while under different circumstances another mine will be the most efficient producer for the same customer [PENSWICK, 2001]. Therefor in the future the most profitable mining companies will be those who have permanent ?real-time? control on their actual production cost level. Certain approaches are under way to provide reliable modeling tools for aiding mining companies in highly complex decision finding procedures. A high potential for enhancing efficiency is the integration of all single steps of the mining working chain into a production process structure to make advantage of an optimized flow of material and information through the ?moving ore factory? [WIGDÉN, 2001]. Crucial to all these activities is the ability of getting reliable, just-in-time information from the entire mining production chain. As modern mining machinery today is controlled electronically and even already operated autonomously, the theoretical preconditions for the data acquisition is already fulfilled. But up to now, there was no way of cost effectively exchanging the process information with databases, simulation tools and other enterprise level software. Any data exchange problem had to be solved by individual and expensive software development projects. To solve these problems, the International Rock Excavation Data Exchange Standard (IREDES) was launched in 2000 by major players in the industry. The task of this initiative is to define a ?common electronic language? for easy and standardized data exchange between mining machines and central computer systems. As in other industries, this standard is expected to have significant impact on the use of automated equipment. It shall provide easy ways of using multi vendor machine installations in data controlled mining processes. At the same time it reduces cost for individual development of interfaces for all parties involved. The standard?s technical architecture is flexible and open - also for future applications. It uses modern technology enabling easy data exchange with commercial databases as well as open on line networking.

"In today’s world of complex projects, where engineering and execution are supported by a high level of project management and systems, how critical is the human factor in design engineering. Based on his involvement on a variety of projects, Tony Lipiec will relate his experiences as the impact of 4 factors: the ‘team’ involved in the design and execution of the project; the project and information systems supporting the project; the impact of scope, time, and budget; and finally the selection of the proper success criteria to judge the project and the people who have enacted the project.The discussion of the team will relate to the quality of people and the impact of their knowledge, attitude and experience. It will also look at the relationships and interests of the various stakeholders. Decision making and taking responsibility will be discussed.Supporting the team are the management, document and information systems. The value that these systems bring to the project as a whole will be examined. How project size impacts the applicability of the systems will be discussed.Scope, time and budget are recognized as critical. Reference will be made to the interplay between these components which are vital to project success. The issue of iterative design and whether it is necessary will be considered together with the development of supporting technical information.Finally the selection of the proper success criteria and the awards provided to the team can have a big impact on the final, production success of the project. The author will discuss his views on the impacts of these on EPCM projects."
