Изобретение относится к металлургии тяжелых цветных металлов, а именно к выщелачиванию из руд и концентратов соединений металлов растворами серной кислоты в присутствии окислителя. Цель изобретения - повышение степени извлечения металлов в раствор и увеличение содержания свинца в остатке от выщелачивания. Известные флотационные способы не обеспечивают селективности перехода сульфидов в одноименные концентраты. Способ выщелачивания концентратов в растворе серной кислоты в присутствии окислителя - пероксодисерной кислоты нецелесообразен, т. к. требует специальное производство для ее получения. Предлагаемое техническое решение позволяет обеспечить удаление балластных и вредных составляющих концентрата с применением диоксида свинца, извлекаемого из лома аккумуляторов. Способ включает обработку в растворе серной кислоты и последующую фильтрацию для отделения сульфатов.The invention relates to the metallurgy of heavy non-ferrous metals, namely to the leaching of metal compounds from ores and concentrates with solutions of sulfuric acid in the presence of an oxidizing agent. The purpose of the invention is to increase the degree of extraction of metals in the solution and increase the lead content in the residue from leaching. Known flotation methods do not provide the selectivity of the transition of sulfides in the same concentrates. The method of leaching concentrates in a solution of sulfuric acid in the presence of an oxidizing agent — peroxodisulfuric acid — is impractical, since it requires special production to produce it. The proposed solution allows for the removal of ballast and harmful components of the concentrate with the use of lead dioxide extracted from scrap batteries. The method includes processing in a solution of sulfuric acid and subsequent filtration to separate the sulfates.
