XV CMMI Congress
1570
Calendm"
About 140 participants, attended the Symposium. The conference and associated exhibitions were very well organised. The annual conference in the Western Cape, as mentioned previously, is usually a great meeting place for mineral processors, both academic and industrial from mainly South Africa. This meeting was no exception. Twenty seven (27) papers and twenty (20) posters were presented at the symposium. The papers were overall of a very high quality and delagates received a booklet containing the abstracts of papers and posters at the symposium. The Annual Dinner of the Western Cape Branch was held at the same venue on the second evening of the symposium. The guest speaker was Mr Michael Spicer from Anglo American Coq~oration. He talked about the importance of the mineral industries in the New South Africa. There was general consensus from both the delegates and guests that the quality and sincerity of his message was outstanding. Four SAIMM student prizes to the best final year students in Mineral Processing at the Universities of Stellenbosch, Cape Town and Cape Technikon as well to the best Materials Engineering student at the University of Cape Town were also awarded by the President of the SAIMM, Dr Hugh Scott-Russell, to Messrs D Annandale and P. Amm as well as Ms S. Vismer and Ms S Kruger, respectively. Mr Rob Dunne, Consulting Metallurgist at Newcrest Mining in Western Australia, delivered the keynote address on two decades of mineral processing in Australia: achievements and ft, ture objectives. He referred to major advances in mineral processing operations in Australia, with special emphasis on the importance of the Australian Mining Industry to the overall production of commodities in the world. The ever decreasing mineral contents of new ore deposits, and in some cases lower commodity prices, require mining operations to become more efficient. In Australia this led to changes in process flow sheet design, development and analytical equipment as well as alternative mining chemicals. He also dealt in detail with the structures for mineral processing research funding in Australia. During the morning session of the first day various papers on comminution were presented which include new milling technologies and the development of control systems. This was followed by some excellent papers on bio-leaching and environmental engineering, which includes topics such as the solidification and stabilisation of hazardous industrial wastes. The afternoon sessions were dedicated to various aspects of flotation. The second day started with hydrometallurgy. These included research papers featuring the recovery of metal cyanides using ion-exchange resins, selective extraction of species from insoluble solids with ion-exchange resins, etc. This was followed by two excellent and very well received sessions on process control in mineral processing plants. Two papers from Stellenbosch on the use of videogral~hic inaage analysis to control and characterize flotation froths and to control hydrocyclones received a lot of attention and interest. Other papers in these sessions included subjects such as the controlling of repulp sections on plants, the review of evaluation models for the sampling of platinum containing ores, the application of intelligent control to an industrial ROM milling circuit and the conversion of the Palabora anode furnace from log poling to hydrocarbon poling. In general it was a very useful and well organised symposium. As already mentioned, the abstracts of the papers are available from Mrs Meg Winter, Conference Secretary, Department of Chemical Engineering, University of Cape Town, Private Bag, Rondebosch, South Africa. The 14th Annual Mineral Processing Symposium will be held on 3 and 4 August 1995. L. Lorenzen XV C M M I Congress Sun City, South Africa, 4-9 September 1994 The fifteenth Council of Mining and Metallurgical htstittttions Congress which was organized by the South African Institute of Mining and Metallurgy and the Geological Society of South Africa in collaboration with the Chamber of Mines of South Afi'ica, was held at Sun City near Johannesburg in South Africa. The theme of the con,_,ress was "Resources and Technolo,,y" which hiuhliuhted the importance of basic technical operations in the efficient managenlent and utilization of resources. The conference coincided with the 100th anniversary of the South Afi'ican Institute of Mining and Metallurgy.

More than 800 delegates from all over the world attended the conference. The diverse nature of the technical presentations necessitated the undertaking of four parallel sessions, viz. Mining, Metals Technology, Extractive Metallurgy and Geology. The minerals industry in South Africa is characterized by deep-level gold mining and this issue was reflected in several of the papers presented in the Mining session. Other papers in this session addressed the uncertainty of the cost of mining at extreme depths, as well as issues such as pumping, hoisting, transport, etc. Papers were organized in 7 categories, namely Mining Overview (5 papers), Mining Narrow Tabular Deposits (10 papers), Rock Engineering (4 papers), Opencast and Massive Mining (8 papers), Mine Planning (3 papers), Eduction (4 papers) and Coal Mining (8 papers). In Extractive Metallurgy the focus fell on a wide range of issues, viz. resin-in-pulp gold recovery, heavy medium separation, bacterial leaching, pressure oxidation, artificial intelligence, etc. Papers were organized in 4 sections, viz Flotation Research and Development (2 papers), Mineral Processing and Bem~ciation, Mineral Processing and Hydrometalhtrgy, Base Metals, Enviromnent (10 papers), Concentration Methods, Bacterial Oxidation Technology, R~'acto#y Ore Developments (10 papers), Commimttion Simttlation and Control, Comminution Developments (6 papers. Several international authors addressed the topic of Metals Technology. hmovations were reflected in a wide spread of presentations, covering mathematical modelling, physical metallurgy, ferrochronfium production, corrosion and pyrometallurgy. Papers were organized in 4 categories, namely General (4 papers) Mathematical Modelling/Simulation, New Processes (9 papers), Physical Metallurgy, WeMing, Corrosion (9 papers), Pyrometalhtrgy, Ferrochrotnittm Production (7 papers). The presentations in Geology were among others concerned with advances in the identification of ore resources, remote exploration techniques, ore reserve calculation, etc., and consisted of both individual case studies, as well as broad review papers. Papers were organized in 4 categories, namely The Witwatersrand Basin (4 papers), Witwatelwrand Case Histories, Witwatertrand Ore Body Modelling, Coal Case Histories (10 papers), Plati#lttm Case Histories, General Topics, Base Metal - Exploration and Case Studies (9 papers), Geoph3wics - The Vibroseis Technique, Geophysics and Mine Plamting (5 papers). Social events included the welcoming banquet on Monday night, as well as a tarewell beach party at the spectacular Lost City resort. Affiliates were treated to a full programme which included early-morning and late-afternoon game drives in the African bush, tTlshion shows, theatre extravaganzas, as well as excursions to various other places of interest in South Africa. The conference was concluded by Mr Pik Botha, Minister of Mineral and Energy Affairs, who gave an excellent layman's perspective of the importance and pervasive role of minerals in society. After tile conference, many delegates had tile opportunity to visit other places of technical and general interest in South Africa, Botswana, Namibia and Zimbabwe. The proceedings were published in three volumes (Synll~osium series S 14) by the SAIMM, viz. Mining (vol 1, edited by H.W. Glen, ISBB 1-874832-35-8), Metals Technology and Extractive Metallurgy (vol 2, edited by H.W. Glen, ISBN 1-874832-39-0) and Geology (vol 3, edited by C.R. Anhaeusser, 1874832-40-4). C. Aldrich
