Abstract

Данная заявка относится к способам извлечения металлов из сульфидов металлов, которые включают приведение в контакт сульфида металла с кислым раствором сульфата, содержащим сульфат трехвалентного железа и реагент, который имеет тиокарбонильную функциональную группу, где концентрация реагента в кислом растворе сульфата является достаточной для повышения скорости экстракции ионов металла относительно кислого раствора сульфата, который не содержит данный реагент, с образованием продуктивного раствора, содержащего данные ионы металла.
