The new field of environmental investiga tions introduces new problems of ethics, res- ponsibility, conflict of interest and technical procedures. Such investigations involve four elements: developer, consultant, approving authority and the public. It is essential that the consultant provide technical competence, speed and efficiency, impartiality and credibi- lity. Despite allegations to the contrary, it is not in the consultant's own best interest to omit, ignore or obscure significant adverse en vironmental impacts.

The paper deals with the effect of sodium polysulphides in chrysocolla flotation. Activity of elementary sulphur adsorption on the mineral surface is discussed. The mechanism of polysulphide action in the process of sulphidisation and formation of sulphur on the mineral surface is proposed. Sodium pentasulphide is shown to be the most effective modifier of chrysocolla flotation.

In the 25 years since Broken Hill's 75th Anniversary which was marked by an Australasian Institute and Mining and Metallurgy Conference in Broken hill, there have been some significant changes in the role of mines inspectors. This paper updates the information given by the then Chief Inspector of Mines, J.H. Burford, to that 1968 Conference, with an emphasis being placed on mines inspection, although it also reflects changes to mining legislation and regulatory bodies.

The Key Issues - An Overview Minerals industry needs Mining companies want technologies which are ò cost-effective, ò high likelihood of delivery (ie transfer existing technologies from other industries), ò highly useable, ò an evolutionary rather than revolutionary approach, and ò to be developed in partnership with the mine, supply groups and researchers, For example, `soft' systems for information collection to better manage the mining process rather than mechanical systems.

There has been much debate in the past as to whether the Australasian Institute of Mining and Meteorology ("AusIMM") should issue valuation guidelines in addition to the ASX and NCSC requirements. My experience in preparing independent expert reports has been that "best practice" sets higher standards than any laws or requirements set out by the ASX and NCSC. This is where I see the AusIMM coming in.

Successful management is ultimately measured by return on shareholders' funds. This is the inescapable and inexorable discipline that ultimately rules every investment. Shareholders today are predominantly, and increasingly, the superannuation funds and insurance funds of almost all of us. We have already reached the situation in Australian investment history in which the best interests of employees can be very directly identified with the best interests of the owners of the capital invested.

The Paracale gold region had been known for hundreds of years, but the first professional attempts to work the lode and alluvial deposits were made only in the 1890s by the London-based Philippines Mineral Syndicate. Complex ores, transportation problems, and the Philippine Insurrection halted operations. Ultimate success went to American firms, though Frank Karuth's Philippines Mineral Syndicate had pioneered the field.

The purpose of this paper is to review recent approaches by regulators, employers and employees and their associations to the introduction of flexible employment practices and the management of fatigue related risk. More importantly, it will focus on developments in our law either through legislative change and cases which have dictated trends. The paper particularly considers the limitations imposed by occupational health and safety legislation to resist or limit the move to flexible workplace practices on the basis that such practices are unsafe.

The Republic of Kazakhstan has well developed mining and metallurgical complex. In modern conditions, when deposits of useful minerals are running thin, it is very important to find additional sources for obtaining necessary products. As our investigations showed different kinds of waste may be used for producing of different kinds of products, which are successfully applied in different branches of KazakhstanÆs economy. Analysis of ways for increasing of complex use of mineral raw materials of different deposits, widening raw mineral materials base and decreasing negative effects on the environment, are presented in this paper.

Circuit alterations and adoption of more compact items of equipment have made it possible to increase the capacity of the King Island Scheelite concentrator, both with regard to head grade and feed tonnage, while at the same time increasing total recovery and reducing maintenance costs. The present operation is described, with particular emphasis being placed on alterations made during the last two years to achieve capacity Goals.

Traditionally mining and conservation have been regarded as opposing and mutually exclusive concepts of land use. Often problems are anticipated which cannot be substantiated by facts. In addition, an ill defined time-scale adds to potentially emotive issues. Examples from Australia and elsewhere are presented which illustrate the dynamic nature of the environment and accentuate sequence patterns in plant community development following natural and man-made disturbances. The mining industry generally appears to be aware of the environmental impact of mining and whilst endeavouring to minimise the disturbance, is still orientated towards maximum production.

The aim of the study was to determine the ranges of stability and instability of the metal hydroxides and metal cyanide species that may be formed during the gold extraction process, Merrill-Crowe gold precipitation, and Inco S02/Air or ferrous ion cyanide removal processes.Following cyanide detoxification by the Inco S02/Air process, the main components of concern in the tailings will be:

An attempt was made to determine the lateral extent of analcite in the Newcastle Coal Measure sediments of the Sydney Basin. From an examination of the cores of eleven bores it was concluded that the mineral is concentrated in the western sector of the original Newcastle Basin and this presumably was the region of greatest sodium concentration and aridity. The distribution of the analcite is such that it appears to have little correlative value.

Management at all levels continually strive to optimise, or make the most of resources available to them. Daily, decisions are being made on how to most efficiently locate and exploit an ore body, then process and market the recovered metal. At one level this optimisation process in the Australian mining industry appears to be successful, for example, witness the improvement in productivity and reduction in operating costs through the 1980s. Yet, at another level the industry's performance has been appreciably below expectations as measured by rate of return criteria. Companies likely to exhibit superior performance are those that are able to co-ordinate, through good planning, the optimisation process at all levels of the organisation. An important role for general management is therefore to provide the context or boundary conditions in which optimisation can Proceed.
