Selective Dissolution and Mechanism of Arsenopyrite by the Oxidizing Agent in Alkaline Leaching System

Selective Dissolution and Mechanism of Arsenopyrite by the Oxidizing Agent in Alkaline Leaching System

Arsenopyrite is a common gold-bearing mineral, and the presence of arsenic leads to difficulties in gold recovery. In this paper, the effects of leaching time, NaOH concentration, temperature and potassium permanganate concentration on the arsenic leaching rate in the process of arsenopyrite arsenic...
