Способ относится к технологии переработки золотосодержащего сырья и позволяет извлекать драгоценные металлы из упорных руд и концентратов. Руду или концентрат перемешивают с твердым материалом, содержащим марганец в окисленной форме, например пиролюзит, в растворе минеральной кислоты, например серной, в присутствии серо- и железосодержащего материала, например пирита, арсенопирита или других природных соединений серы и железа.The method relates to the technology of processing gold-bearing raw materials and allows you to extract precious metals from refractory ores and concentrates. The ore or concentrate is mixed with a solid material containing manganese in an oxidized form, for example pyrolusite, in a solution of a mineral acid, for example sulfuric, in the presence of sulfur- and iron-containing material, for example pyrite, arsenopyrite or other natural sulfur and iron compounds.
