ABSTRACT
Presented results for sulfate-reducing bacteria and products of their metabolism, as flotation regulators of sulfide minerals and ores, and solvents of antimony-and tin-containing concentrates. Thiobacillus ferrooxidans used for selection of Hg minerals from antimonite and for transformation of antimonite into senatmontite - commercial product of antimony trioxide. The microbial fat and lipides of different fungi and algae were effective as collectors for non-sulphide ores - for fluorite, scheelite and phosphate ores. The biomass as flotation reagent also studied for celestite and associated minerals. Were established conditions of efficient transformation of strontium sulfate in its carbonate using adapted SRB
