Low-Temperature Dry Chlorination of Sulphide Ores — A Review
CIM Bulletin, Vol. 71, No. 791, 1978
H. W. Parsons, Research Scientist, CANMET, Department of Energy, Mines and Resources, Ottawa, Canada
Several low-temperature, dry chlorination processes for the treatment of sulphide minerals are reviewed, in a chronological order. These processes include the following: the Swinburne-Ashcroft, Baker-Burwell, Malm, Comstock-Wescott (Aldermac) and the Mitterburg Mining Process. Dry chlorination investigations at the Canadian Mines Branch (now CANMET) and the U.S. Bureau of Mines are discussed, as is a proposed process by the South Africa National Institute for Metallurgy. The techniques used in the process are discussed, as are the shortcomings, problems and failures of the methods.
