The sizing and classification circuits at the Mt. Newman Beneficiation Plant have performed satisfactorily. Investigations have been aimed at solving minor problems and achieving small' improvements. Emphasis has been placed on cost reduction rather than metallurgical performance. It has been found that some circuits will give better performance with the sieve bends removed. 1.0 BACKGROUND Mt. Newman. Mining operates a major iron ore mine in the Pilbara region of Western Australia. Rainfall is sparse (average 250 mm/year). Current mining is all above the water table. What rain there is tends to run off quickly instead of soaking in. The total operation produces about 30 Mt/ year of saleable product. Most of this product comes from high grade crushing plants where ore from the quarries is simply crushed and conveyed to product stockpiles. About 3 Mt/ year comes from the Beneficiation Plant.

The model, already tested and applied, enables a highly efficaceous solution of the problem of issuing instructions for interested services on the basis of known contents of in- dividual stages of mine mechanization repair and known time intervals between repairs for specific machines and total mechanization. Application of the model provides work orders for all types of repairs for specific machines or systems, and orders for the commercial department regarding spare parts Supply.

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.

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.

Congratulations on your considerable enterprise in securing the opportunity to have this international conference here in Brisbane - and congratulations on your success in attracting such a distinguished audience from so many nations, with such a broad selection of papers. It is a notable achievement that in the year in which Australia is celebrating two hundred years since settlers first came fran Britain, The Australasian Institute of Mining and Metallurgy is responsible for some ten major conferences, of which at least four are specifically international, or have a very strong international involvement.

One of the often overlooked factors affecting the capital investment decision in new or existing plants is the value of stock holdings necessary to maintain the plant. This paper puts forward a simple decision matrix on whether a part should be stocked depending on 1. the criticality of the item of equipment in terms of the effect on cash flow of its failure, 2. the lead time of the part, and 3. the stock holding value if it were Stocked.

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.

Operation of the tankhouse at the Electro lytic Refining and Smelting Company's works has been improved, but further automation is re- quired to cut the labour intensive nature of the routine tasks. Anode quality, both chemical and physical, plays an important role in efficient refinery practice, and impurities such as lead, antimony and nickel have required careful monitoring for smooth operation. The gradual replacement of copper blanks by titanium has markedly improved the quality of starting sheets, but problems have been ex- perienced with surface preconditioning of the titanium blanks. Polishing with emery paper proved to be a successful technique.

I am honoured to have been asked by Sir James Foots, the President of the Congress Organising Committee, to open this, the 13th Congress of the Council of Mining and Metallurgical Institutions. The theme you will be addressing over the next few days is "The Twenty First Century - Mining, for Mankind" - a theme that must be regarded as an enormous challenge for the entire minerals industry. Previous conferences, starting in 1924 in London and followed by two others in the United Kingdom, have also taken place in Canada (three), Southern Africa (three), Australasia (two), and Hong Kong (one), but this is the first to be held in Singapore.

It is a great privilege to be invited to give this address at this centenary conference. A centenary is a time for recollection, for celebration and for looking ahead. The AusIMM has much to celebrate and many things to recall. I hope in this address to make some useful comments about Australia's future (and mindful of but not forgetting New Zealand), looking ahead for 25 years or so, and the mining industry's role in that future.

Economies in cemented fill demand the utilisation of the full potential of the portland cement component of the mix. If declined tailings are used, it is desirable to establish the optimum particle size distribution. Pozzolic materials and slags are. very useful additions to increase the amount of cementitious material through reaction with calcium hydroxide produced by hydration of the cement. It is also essential to check out the presence of substances which may seriously affect the setting and hardening of the cement or the durability of the cement bond. The importance of quality control in the preparation of cemented fill cannot be over Emphasised.

Its two years since we have presented at this conference and since that time we have made significant progress with our coal developments in New Zealand. In 2005 we held the Whareatea West exploration permit and had just completed the purchase of the Cascade mine. Today, in addition to Cascade and Whareatea we now have the Takitimu Mine, Eastern Coal Supplies, our coal blending and distribution facility in Timaru, prospecting permits at Ohai and Orepuki and an established customer base underpinned by the contract to supply FonterraÆs Clandeboye plant commencing in September 08. For this presentation I would like to take you through our purchase and development of the Takitimu mine.

The application and development of monitoring and control techniques of coal mines in China is mainly described in the paper.The techniques of mine control and monitoring system have been developed as an important means of production dispatch, command and management with ever-increasing coal production and gradual raising of the level of mechanization and centralization of continuous mining. The continuous stage monitoring and control system in China coal mines has been developed from the initial single fixed plant monitoring, and the technique of computers has also been applied in the system for productive and environmental monitoring, featuring a new type of mine control and monitoring equipment of China.

A study has been made of the influence of bentonite type on the wet strengths, dry strengths and drying rates of pressed iron ore pellets. Measurements of the influence of bentonite on the kinetics of growth of pellets are also reported. The results show that bentonite decreases the rate of growth of pellets and the drying rates of pellets while increases are observed in both wet and dry strengths. The results have been interpreted in terms of the physical and chemical charact- istics of the bentonite and the suitability of a given bentonite for particular pelletising operations has been discussed.

The Australian mining industry has suffered from a decline in its public image during the past decade. This has occurred partly as a result of increased questioning of accepted social and economic values since the mid-1960s and the greater restrictions placed on industry since then, and partly ò from the industry's inability to effectively answer its critics. Public opinion surveys have shown the depth of the decline in the industry's community acceptability and highlighted those issues which people regard as disadvantages of mining. The industry's poor public image has contributed to the difficulties of attracting young people to take up professional careers in mining. All those involved in the industry have a responsibility to assist in activities designed to improve the industry community Acceptability.

Perseverance Mine is a part of Leinster Nickel Operation (LNO), a fully owned division of Western Mining Corporation (WMC). The town of Leinster is located 370 kilometres north west of Kalgoorlie. LNO operates an underground gold mine and mill at Agnew, 30 kilometres west of the town in addition to two nickel mines and a mill 15 kilometres east of Leinster. Both the Perseverance and Rocky's Reward nickel orebodies are mined by open pit and underground methods.The Perseverance orebody was discovered in the early-1970s. Decline development commenced in 1977 and the first ore was milled in 1978. The shaft sink started in 1979. The shaft was comissioned in 1983, four years after sinking commenced. The mine was placed on care and maintenance in 1986 and purchased in January 1989 by WMC.

The curbing of expansion in tertiary level education in Australia and the question- ing of its objectives which are now occurring are likely to have important effects on mining and metallurgical education. Student enrol- ments are low but the serious shortage of specialised minerals industry graduates pre- dicted during the boom of the late 60's has not eventuated. Other manning problems of a less quantitative but possibly equally import- ant kind have been identified. They point to a need for a full and deep review of the education and training programmes available to Australian graduates planning to enter product- ion areas of the minerals industry. An alter- native educational structure providing greater flexibility is suggested.
