Production Practice of Deep Impurity Removal in Anode Furnace Refining
In response to the high impurity copper ore powder containing arsenic and antimony,the crude copper produced by traditional pyrometallurgical refining cannot effectively remove impurities such as arsenic and antimony.Based on production practice,technicians adjust the addition method and amount of alkaline sodium carbonate to make the w(As)＜0.2％,w(Sb)＜0.15％,and the chemical indicators meet the electrolysis requirements.
