FIELD: metallurgy.
SUBSTANCE: method of processing refractory pyrite-arsenopyrite-pyrrhotite-antimonite gold ore (versions) refers to metallurgy of noble and heavy nonferrous metals. Substance of invention consists in fact that in all versions pyrrhotite concentrate, pyrite-arsenopyrite concentrate antimonite concentrate and tails collective flotation are obtained. At that, method involves production of crushed ore or tailings of gravity, directed to collective flotation. Method applies magnetic separation.
EFFECT: technical result is increased through extraction of gold, providing efficient mineral raw material, reduction of capital and operating costs by creating technology for processing refractory pyrite-arsenopyrite-pyrrhotite-antimonite gold-bearing ores.
