Комбинированная схема окисления золотосодержащих сульфидных руд и концентратов

Комбинированная схема окисления золотосодержащих сульфидных руд и концентратов

Abstract

It is shown that preparatory photoelectrochemical oxidation allows to improve completeness of mineral matrix opening with its further bacterial oxidation. Also it helps to increase the efficiency of dispersed gold extraction from sulphide ores. Oxidation composite circuit laboratory tests have been done as well as half-industrial tests on electroactivation sorption dispersed gold leaching out of Kokpatas deposit sulphide ores. Gold extraction increase with application of composite technology of sulphides and arsenopyrites oxidation makes up 23 %

Показано, что предварительное фотоэлектрохимическое окисление позволяет повысить полноту вскрытия минеральной матрицы при последующем бактериальном ее окислении и повысить показатели извлечения дисперсного золота из сульфидных руд. Выполнены лабораторные исследования комбинированной схемы окисления и полупромышленные испытания электроактивационного сорбционного выщелачивания дисперсного золота из сульфидных руд месторождения Кокпатас. Увеличение извлечения золота после комбинированной технологии окисления сульфидов и арсенопирита составило 23 %
