Over 200 delegates attended the SAIMM Colloquium on Flotation, which was held at Mintek on 22nd September, 1983. In introducing the programme, the Chairman of the Technical Programme Committee, Mr Eugene Fivaz, said that an attempt had been made to strike a balance between theoretical and practical papers, which he hoped would provide something for everyone. He wished to record in advance the thanks of the Institute to S.A. Cyanamid for sponsoring the lunch, and to Bateman Equipment Limited for the cocktail party to be held at the end of the day's proceedings.

The National Institute for Metallurgy was the venue for a one-day colloquium on 'The Chemistry of Processes for the Recovery of Gold on Activated Carbon'. Organized by the South African Chemical Institute (Southern Transvaal Section) in collaboration with the National Institute for Metallurgy (NIM) and the South African Institute of Mining and Metallurgy, the colloquium attracted tremendous interest from the mining industry. Some 300 metallurgists, engineers, and chemists were brought up to date on advances in this technology made by scientists of NIM and the Anglo American Research Laboratories (AARL).

A school on the principles and practices of ladle metallurgy, organized by the Technical Committee: Metals Technology of The South African Institute of Mining and Metallurgy, was held at the University of Pretoria from 13th to 16th November, 1989. The course leader, Professor R.J. Fruehan from the Carnegie Melon University, Pittsburgh, Pennsylvania, presented the main part of the course. Three papers were read by local steelmakers on the experience gained in the field of ladle metallurgy in South Africa. The School also included a special half day seminar on new and innovative steelmaking and casting processes presented by Professor Fruehan.

To B. K. Martus I discussed several points raised by Mr Martus in my reply to Professor Krige*. Mr Martus discusses several possible interpretations of optimum South African sales, but in my paper these sales refer to the sales level that maximized the working profit of the whole South African gold-mining industry over the past eleven years. Mr Martus also seems to be under the impression that the paper deals with the future. While there may be references to the future, and some implications for the future may be obvious, the paper deals essentially with the past eleven years.
