METHOD OF PROCESSING REFRACTORY PYRITE-ARSENOPYRITE-PYRRHOTITE-ANTIMONITE GOLD ORE (VERSIONS)

摘要

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.;12 cl, 12 dwg, 4 ex
