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.

The role of metallurgy in enhancing beneficiation

2013-10-29 · The gold is extracted from the cyanide solution using activated carbon. The gold is removed from the activated carbon into a solution. This solution undergoes electrowinning to deposit the gold onto steel wool, which is then smelted into an impure gold bar. These impure bars are sent to the Rand Refinery for final treatment to produce pure gold.
