Abstract

Several flotation strategies for arsenopyrite have been developed over the last two decades. For refractory gold ores containing arsenopyrite, these flotation techniques have been found to have some limitations. Pretreatment of the ore is necessary to enhance arsenopyrite flotation and thereby increase gold recovery. In the present study, ultrasonic treatment was used as a pretreatment for enhancing arsenopyrite flotation. Pretreatment of naturally oxidized arsenopyrite change...
