PROCESS OF FLOTATION OF SULFIDE GOLD-CONTAINING ORES

摘要

FIELD: mineral dressing. SUBSTANCE: process that can be used for flotation of sulfide gold-containing ores as well as complex ores involves conditioning of pulp with xanthogenate and auxiliary collector, in particular concentrate of ketosulfides: mixture of 3,7-dimethyl-5-thianonan-2,8-dione, 3-methyl-5-thiahexan-2-one, 3-methyl-3- thiaheptan-2-one, 3,6-dimethyl-5-thiaheptan-2-one, 3-methyl-thiacyclohexan-4- one, 1,4,5-trimethyl-7-nhiabicyclo(2,2,2)octan-2-one, and isomers of 3,4,6- trimethyl-2-cyclohexen-1-one. The latter is added in amount 25-50% of the total consumption of collectors. EFFECT: improved flotation characteristics. 2 cl, 1 tbl
