摘要：

The authors propose the process for selective flotation of auriferous pyrite and arsenopyrite, where the combination of xanthate, 2-hydroxylpropyl ester of diethyldithiocarbamate acid (HPEDEDCA) and oak-bark extract (OBE) is used to produce pyrite concentrate recovered into the froth product. The process provides the selective recovery of valuables into heteronymous concentrates, thus reducing the irrecoverable valuable component loss by 5-7 %. The complexing capacity of HPEDEDCA to gold is experimentally proved and allows using it as a selective collector of auriferous iron sulfides. The use of OBE to depress iron sulfides and arsenic in flotation of multicomponent ores contributes to higher flotation selectivity and grade of heteronymous concentrates. © 2011 Pleiades Publishing, Ltd.
