RT Report T1 Environmental Aspects of Nickel Production: Part I. Sulphide Pyrometallurgy and Nickel Refining - A Technical Review A1 United Nations Environment Programme, K1 nickel K1 air pollution K1 water pollution K1 pollution control K1 particulate matter SN 92-807-1133 4 YR 1987 FD 1987 LK https://wedocs.unep.org/handle/20.500.11822/28505 UL https://wedocs.unep.org/handle/20.500.11822/28505 NO This technical review covers the most comnionly used methods of extractive metallurgy and the equipment to produce nickel and nickel products. It is divided into two parts: Environmental Aspects of Nickel Production - Part I: Suiphide Pyrometallurgy and Nickel Refining; and Environmental Aspects of Nickel Production - Part II: Laterite Pyrometallurgy and Hydrometallurgy, and Ferronickel Smelting. (To be prepared separately). The review is concerned with the environmental aspects of these technologies and presents information either as four.d in technical literature or as made available by companies, governmental agencies, and individuals expert in the field.
