Batch and continuous oil-phase agglomeration techniques have been successfully applied to the beneficiation of a low-grade gold-bearing sulphide ore. Grades of 9-10 ozton were obtained at the natural pH of the ore, representing at least a 50-fold improvement. Recoveries of up to 95 per cent were realized, with the gold content in tailings reduced to less than 0.01 ozton 0.3 ppm.

Some sulphide ores undergo oxidation by air to form sulphates. This explains the occurrence of sulphate ores. Ores are invariably found in nature in contact with rocky materials. These rocky or earthy impurities accompanying the ores are termed as gangue or matrix. Some important ores and the metals present in these ores are listed in Table 18.1
