One of the great attractions of academic life, for those who enjoy the opportunities of university teaching, is the continual contact with some of the most able young minds which each rising generation produces. So when I was asked to give a paper at t

As the awareness and concerns on subsidence issues increase, there are clear, challenging and credible community expectations for responsible mining, public safety, optimal resource recovery and effective land use and environmental management, coinciding with a changing and strengthening regulatory environment being implemented by the NSW Government. This paper discusses a number of areas where cultural changes in the mining industry will assist with improved subsidence management to meet the enhanced standard.

Lime is the common reagent used for pH control in cyanide gold circuits. Lime can be supplied as either quicklime (CaO) or 'hydrated lime(Ca(OH)2). Both are dry powders with variable flow properties. These properties demand special attention when designing machin- ery to handle them.

Mr. Champness: I wish to congratulate the authors on their paper, which covers a large variety of subjects. Not every mine is in the fortunate position to effect cost reductions by the sinking of a new shaft, but, as the authors have endeavoured to show in their paper, with improved techniques further reductions are possible. I would like to ask two questions. Can the authors give me an approximate idea...

The QEM'SEM system for automated image analysis of mineral samples is described. Details of the equipment are given together with information on the methods of measurement. Finally some practical applications are described where QEM*SEM has been used for the solution of metallurgical Problems.

The general characteristics of bauxite deposits in Temporary Reserves held by Bauxite Exploration Pty. Ltd., Western Australia are briefly reviewed. The deposits (slide) are 'near the eastern limit of the bauxite laterite cap which masks the basement rocks of the Darling Range.

Contract mining is an integral part of the underground and surface hard rock mining industry in all states of Australia. Contract mining is now makes a major contribution to the opencui coal industry in Queensland and New South Wales with Thiess alone producing over 16 million tonnes per annum with safety performances that most coal companies would be proud of. Contract mining is now attracting interest in the underground coal sector.

In his introductory remarks Mr. MacKellar referred to three types of development which may be considered to compete with mining for land use. 1. Total Development - in which he cited urban development, and intensive agriculture. 2. Partial development - in which he cited pastoral, and in this category would come National Parks. 3. Non development - in which category would fall the primitive or wilderness areas.

In recent times there has been a marked increase in public awareness of air pollution. Some of this has been induced by the Press but our own senses tell us that there is a visible haze over our cities on many mornings. The people are now demanding a clean environment and will no longer tolerate smoke and dust fall or gaseous and odorous emission which either soil building and furnishings or interfere with comfort and well being.

This paper describes the structure, performance, principle and effectiveness of a new laboratory type of composed-forces field separator utilising the composition of the magnetic force, vibrating force, pulsating force, gravity and fluid-viscous force etc to separate fine feebly magnetic valuable minerals. Compared with the pulsating high gradient magnetic separator, this separator possesses unique advantages of higher enrichment ratio and higher recovery of the magnetic component.

The paper presents an algorithm for calculating the natural air distribution in a ventilation network (sub-network) on the basis of following data: - for each network branch: labels of starting and ending nodes, label of the branch, resistance and natural depression; - for each fan: the characteristic in the form of a second order equation and initial flow.

Zinc enters into solution on aeration of sphalerite in deionised water. It has been observed that less zinc dissolves in a copper vessel than when the same operation is carried out in a glass vessel of similar shape and size.

The use of electrostatic fields to effect phase dispersion and agitation in solvent extraction (SX) has demonstrated many advantages over conventional mechanical methods and is therefore a very real alternative. Despite this, an industrial application of the technique is yet to be developed. Here, the several variations of the technique that have been proposed are reviewed, the state-of-the-art assessed and key limitations to a commercial application outlined.

Thank you for that introduction and especially thank you to the organisers for inviting me. I've had a considerable interest in this area and I've had the advantage of an education from Neil on the subject of offering documents as a result of our collaboration together on the Securities Information Review Committee.

After the last world war, management tended to change from an acquired skill more associated with experience than formal training, to a specific widely-recognised specialism requiring an involved formal education process.That process, of necessity, required the development of business schools, M.B.A. courses -indeed the setting up of professional chairs to deal with the intricacy of general management development.Management research burst forth bringing forward new and exciting theories which developed new techniques, tools and terms.

Many of the recent major achievements of our industry were visions of our forefathers in the 1800s. Only recently has technology been able to meet the vision of our predecessors. This paper follows the development of selected aspects of tunnelling from the 1800s to present day. It appears that, at the turn of the century, technology is beginning to catch up with our vision and we are able to put our ideas to work more quickly.

A review of the motivation of personnel in the open cut mining industry. The effect of social, geographic, environ- mental, organisational, union and other factors on employees' motivation as assessed from job experience and from an attitude survey. An appraisal of where we should be heading and what influence management can have on the motivation of employees.

The paper considers the factors that will control the importance and the nature of R & D required by the Australian mineral industry over the next decade. The process required to determine the appropriate priorities for research and how it must be managed is described. The work of the Australian Mineral Industries Research Association is used to illustrate this process.
