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'.

The Institute was privileged to receive an invitation from the Armaments Corporation of South Africa (Armscor) for members to visit one of their plants. As these are factories, the number of visitors who could be accommodated was limited. As the opportunity seldom arises to learn something of this very large industry, there was great interest among members and many were disappointed in not being able to go.

The ore mined at Black Mountain is of a complex nature, being composed of both magnetic and massive sulphides, which have greatly varying metal values. Because of this, there is need for a rapid method of assaying for the continuous monitoring and control of the process streams, and the Outokompu Courier onstream analysis system and the Proscon process-control computer systems have therefore been installed. Geostatistics In view of the continuing demand, the Department of Mining and Mineral Sciences in association with Special Courses Division, Department of Adult Education and Extramural Studies, both of the University of Leeds, will offer two further courses on A Practical Introduction to Geostatistics in 1981, each covering ten working days. The courses will run from 30th March to 10th April and 14th to 25th September.
