| Abstract Scope |
In the 1970s, Canada was the world’s leading nickel producing country and Canadian firms had big expansion plans. INCO had major in-house research programs underway developing technologies for laterite deposits overseas and for the nickel and copper refineries in Sudbury, Ontario. Two new laterite smelters were commissioned in the 1970s in Indonesia and Guatemala simultaneously based on the Rotary Kiln Electric Furnace Process. Falconbridge undertook similar programs and commissioned the Falcondo laterite smelter in the Dominican Republic based on the company’s proprietary technology in 1971. In the 1980’s to 1994 the emphasis at the Canadian nickel smelters was mainly driven by environmental pressures to reduce SO2 emissions. From the 1990’s up to the present time, significant environmental operational improvements have been achieved in Canada, and the development of technologies for the laterite deposits for Koniambo and Goro projects in New Caledonia were shaped primarily by energy efficiency and environmental considerations. This paper will review these important developments that enabled the technology advances that were achieved by these companies. Other developments in nickel sulphide and laterite pyrometallurgy will also be discussed. |
