The 8th Annual University of Cape Town (UCT)/ University of Stelenbosch (US) Minerals Processing Symposium was held at the Van Riebeeck Hotel in Gordon's Bay on 3rd August, 1990, under the auspices of the Western Cape Branch of The South African Institute of Mining and Metallurgy. The primary object of this meeting was to give research students at UCT and US the opportunity to present their work to a critical audience from industry, and to obtain feedback regarding the research needs of the minerals industry. Although the emphasis of these symposia is on work in progress at US and UCT, they also create an excellent opportunity for informal discussion between academics and metallurgists in industry. The first symposium in this series was held in 1982 at US, while the symposium in 1989 was replaced by the International Colloquium on Developments in Froth Flotation, also held in Gordon's Bay.

The Federation of Societies of Professional Engineers (FSPE) recently conducted a survey of professional engineering manpower in South Africa. This article presents the data relevant to mining and metallurgical engineering. FSPE in their survey attempted to determine the supply of engineers in South Africa both from local universities and by immigration. The immigrants gave some problems in that it is difficult to know whether a man who claims to be professionally qualified really is. However, it was estimated that the ratio of immigrants who claimed to be qualified to those who really are the equivalent of our local graduates was between 1,0 and 1,9 for mining engineers, and between 2,0 and 4,1 for metallurgical engineers.

"Mining Projects: Evaluation, Finance, and Management" held in May 1980 rounded off a theme started with the colloquium on "Exploration Feasibility Studies and Investment Analysis" held in 1979. Seven papers on various aspects of the potential path of an ore-body from an exploration concept through to discovery, evaluation, and financing, to the management of the construction phase, were presented to the 300 delegates at the colloquium held at the National Institute for Metallurgy.

This Spotlight gives a brief summary of the proposed 1991 tax amendments of relevance to mines and mining houses. It should be read together with the author's article South African mining tax in the 1990's', which appeared in the August 1990 issue of this Journal. A number of tax amendments of relevance to the mining industry were proposed by the Minister of Finance in his March 1991 budget speech. In addition, certain other measures that may be implemented were set out in the budget review document released at the same time. A word of caution is necessary: these measures will become law only if and when they are enacted in the appropriate legislation. When this legislation is tabled in June, it may not contain all of the measures discussed below, some of the measures may appear in modified form, and other measures not discussed at the time of the budget may well appear. Unless otherwise stated, the 1991 tax amendments will affect companies with years of assessment ending in the twelve-month period to 31st March, 1992.

On Tuesday, 10th November, 1987, The South African Institute of Mining and Metallurgy held a colloquium attended by some 120 delegates on 'On-Stream Analysis' at Mintek, Randburg. Mr John Moore, Consulting Metallurgist of Anglo American Corporation of South Africa Ltd, introduced Mr Gene Fivaz, the President- Elect of the SAIMM, who read an address by Mr B.C. Alberts, the current President. Mr Alberts was unable to attend the Colloquium owing to urgent business overseas. Opening The opening address emphasized the important role of minerals in the South African economy. In particular, it was noted that 20 per cent of the work force were employed in the minerals industry or associated industries. In recent years, production costs had risen as a result of inflation, and sanctions had had some effect on the exportation of minerals. Thus, there was continuing pressure on the industry to improve recoveries and increase efficiency.

The past ten years or so have seen many changes in the methods and approach adopted for projects in the metallurgical and mining industry in South Africa. These changes have led to an increased use by operating companies of the project and construction management services offered by engineering contracting companies. For a variety of reasons, this development has been slower in the metallurgical industry than in other areas of production, but that industry is also now showing an increasing trend in this direction.

From its early beginnings, shortly after the Witwatersrand gold rush of 1886, Randfontein Estates was planned as a heavyweight operation. The venture was capitalized by J .B. Robinson to the tune of £2 million at time when syndicates were loath to invest £50000 in ventures in and around the new metropolis, Johannesburg, which had sprung up midway along the Witwatersrand. But by then Robinson was a colossus among his contemporaries. Operating as a loner as he had done on the Kimberley diamond fields, where he created his own individual fortune and commanded the sort of respect which, early in his career, led to his election as Mayor of Kimberley. When news of a third gold discovery in the Transvaal (the first two had been in the Pilgrim's Rest and Barberton areas) reached Kimberley, Robinson's pioneering spirit was further stired and he hastened to the new goldfield to stake his claims before his business adversaries- Rhodes, John X. Meriman, Hans Sauer, and Caldecot-could entrench themselves. Once the new Witwatersrand goldfields had been proclaimed, claimpegging started in earnest. But the question was: where to start? Diamond men al, not one of the financiers had any knowledge of the geology of the gold-bearing formations.

Probabilistic methods for assessing the reliability of engineering systems in mining are the way of the future. So agreed the delegates of a recent short course on the subject, entitled 'Reliability-based Approach in Mining engineering Design'. This was a very successful five-day technical course sponsored by The South African Institute of Mining and Metallurgy and held at Mintek from 7th to 11th March, 1988. The main lecturer for the course was Milton E. Har, Professor of Geotechnical Engineering at the School for Civil Engineering of Purdue University, Indiana, USA. Professor Har was ably assisted by Dr Dirk van Zyl, a former student. Science quiz Teams of pupils from 37 schools within a radius of 12 kilometres of the Council for Mineral Technology (Mintek) competed in a science quiz held by Mintek at its headquarters in Randburg on Tuesday, June 7th, 1988.

Another very successful evening meeting was organized by the Johannesburg Branch of The South African Institute of Mining and Metallurgy on 20th November, 1990, when Mr R.D. MacPherson, General Manager of Richards Bay Minerals, gave a presentation on the Richards Bay operations. The function was held in the Ballroom of the Johannesburg Country Club, and the very high attendance (some 250 people) was indeed a reflection of the high profile of the subject mater. It was also a fitting reward for the efforts of Mr MacPherson and his team, who spent a considerable amount of time and effort traveling the country to present 'the other side of the story'.
