Hydrometallurgical Processing of Gold Ore
https://orcid.org/http://orcid.org/0000-0001-5298-445X
The work is devoted to research on the hydrometallurgical processing of gold-bearing ores using the developed semi-industrial installation. As part of the work, research was carried out on agitation and percolation leaching of ores, as well as the parameters of sorption of the resulting solutions were studied. Mathematical relationships have been established for the dynamics of direct cyanidation. It was found that the ore is favorable for its processing by the method of agitational cyanidation: the extraction of gold into a solution for a size of 95–0.074 mm is 93.56–93.99%. The following materials were used to study the sorption parameters: Norit RO 3515, Chemviron GAC 60-65, Chemviron 205GR 6 × 12, Chemviron 207GR 6 × 12, Purolite S 992, Purolite S 992. The dependence of the concentration of gold in solution and gold recovery on activated carbon was determined on the duration of leaching. It was found that Norit RO 3515 activated carbon possesses the highest capacity and favorable sorption kinetics. When operating at a lower pH level, it is possible to use Purolite S 992 resin as an alternative to Norit RO 3515 activated carbon. This resin at a solution pH of 9.5 showed the best results in sorption kinetics.
