beneficiation of gold ore

THE BENEFICIATION OF GOLD ORE BY OIL-PHASE …

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.
