Abstract PT International Nickel Indonesia, a subsidiary of Inco Limited, mines and processes nickel laterite ores for the supply of nickel matte, primarily to the Japanese market. It has large ore reserves and a substantial portion of its energy requirement is supplied from its own hydro-electric plant. Since the early 1980s, the company has increased its production level and has dramatically reduced its unit costs. Projects are in progress to further decrease costs and recently a major expansion — 31% increase in nominal capacity — has been undertaken, consistent with marketing opportunity in Japan. The expansion project, which has alow capital cost per unit of production, is outlined in this paper.
