Abstract

Способ извлечения ценных металлов, таких как свинец, серебро и золото из остатка, образующегося в процессе электролитического получения цинка, при котором указанный остаток суспендируют и сульфидируют для превращения соединений свинца и серебра в сульфидную форму и далее подвергают флотации для образования флотационного концентрата, который содержит ценные металлы, причем процессы сульфидирования и флотации контролируют электрохимически так, что концентрацию сульфидных ионов, вводимых на операцию сульфидирования, регулируют с помощью окислительно-восстановительного потенциала до значения, при котором образующиеся сульфиды ценных металлов имеют размер зерен, достаточный для их флотации, и что окислительно-восстановительный потенциал на операции флотации устанавливают в интервале, при котором обеспечена адгезия реагента-собирателя к флотируемому материалу, но сульфиды не окисляются.
