COMPOSITION OF REAGENTS FOR FLOTATION ENRICHMENT OF GOLD-CONTAINING SULFIDE ORE Russian patent published in 2023 - IPC B03D1/01 B03D101/02 B03D101/04 

FIELD: mineral processing.

SUBSTANCE: used for flotation of precious metal ores. The composition of reagents for flotation enrichment of gold-containing sulfide ore includes a collector, which is 2-methyl-3-butyn-2-ol, a foaming agent, which is methylisobutylene carbinol - MIBC in an amount of 30 g/t, and an activator - copper sulfate - CuSO₄, in this case, 2-methyl-3-butyn-2-ol is used in an amount of 10 g/t of ore, and copper sulfate in an amount of 50 g/t. According to the second option, the composition of reagents for flotation enrichment of gold-containing sulfide ore includes a mixture of collectors consisting of potassium butyl xanthate - PBX in an amount of 100 g/t, sodium dialkyldithiophosphate - BTP in an amount of 65 g/t and 2-methyl-3-butyne-2- ol in an amount of 5 g/t, blowing agent methylisobutylenecarbinol - MIBC in an amount of 30 g/t, activator, which is used as copper sulfate CuSO₄ in an amount of 50 g/t, and a depressant, which is used as betasulfonaphthalene formaldehyde sodium salt - Orophlos in the amount of 104 g/t.

EFFECT: increasing the efficiency of gold extraction.
