CONFERENCE REPORTS International Conference on Extractive Metallurgy of Gold and Base Metals Kalgoorlie, Western Australia, October 26-28, 1992.
Over 350 participants from a large number of countries attended the conference on Gold and base metals, held in Kalgoorlie, at the Western Mining Company Conference Centre as the main venue. Kalgoorlie is the heart of a major gold and nickel mining region, and with downsteam processing in the form of the Kalgoorlie Nickel Smelter and Kalgoorlie Mint, the city of Kalgoorlie-Boulder was a good location for such a conference. International conferences do require considerable facilities of infrastructure at the place they are held. At the initial stages of planning, the organizers did foresee the difficulties of holding a conference of this kind in a small place like Kalgoorlie; they took considerable efforts to make up the deficiency and made very good arrangements for the smooth and efficient conduct of the whole programme, and deserve all the credit for the same. Apart from technical papers, the conference had 9 plenary presentations with a view to present broader perspectives of important fields. Five of the plenary lectures gave an overview and future prospects of important topics of mineral processing and extractive metallurgy of gold and base metals, two were by way of review of R and D institutions, old and new, and two plenary presentations gave the viewpoint of management with respect to R and D policies. In the technical sessions, 57 papers were presented, out of 62, due to the absence of 5 authors. Major contributions were, understandably, from Australia, but over one-third were from other countries including South Africa, U.K., U.S.A., Brazil, Canada, Papua New Guinea, Germany, Russia and China. Subjectwise, about 30 papers were on gold and the rest on silver, copper, nickel, lead-zinc and general topics like comminution, environmental matters etc. Participants from industry were present in good numbers, leading to good discussions on papers dealing with plant operations, old and new (6 papers), including a plant based on retreatment of old tailings. Mineral processing topics covered (7 papers) gravity processes, flotation, including an application of Jameson cells. Apart from this, there was a paper on high-pressure rolls for gold ores and Prof. Fuerstenau's plenary lecture on comminution. Nickel was discussed primarily in terms of flash-smelting (6 papers including 2 on modelling), so also by the developements in Vanyukov process. In gold technology, apart from the above papers about plant practice, the technical papers covered a variety of topics (17 papers) like pressure leaching and oxidation, bio-oxidation, chloride leaching, column leaching, the effect of surfactants on leaching etc. Two interesting papers dealt with techniques of automated location of gold and fast assay of cyanide-soluble gold. Process mineralogy was the subject of 3 papers. Five papers were concerned with pyrometallurgical processes. Hydrometallurgy of lead, zinc, nickel, cobalt, platinum group metals and copper was dealt with in 8 papers, including an electrometallurgical study. The organization of the conference, including the plant visits was very good, and the publication of the proceeding made available at the conference indicated a painstaking
