FIELD: mining. ^ SUBSTANCE: raw feedstock is ground, and pulp is prepared from it. Pulp is processed with introduction of reagents, a collector and a carrier while mixing, and the produced gold-bearing agglomerate is separated. Reagents added are soda and blue vitriol at the ratio of 1:1. Collectors used are butyl xanthate and thioacylanilide at the ratio of 1:3. The carrier used is polyurethane foam pretreated with transformer oil 1900-2100 g/t. Pulp treatment is carried out in process of mixing with a speed of around 1300 rpm for 80-100 minutes with the content of solid substance equal to 48-52%. Agglomerate is separated by screening and wringing. The gold-bearing concentrate is produced, as well as a cleaned carrier, which is returned for pulp treatment. ^ EFFECT: higher efficiency in recovering fine rebellious gold. ^ 5 tbl |
