美国矿务局提出了处理混合铅锌精矿的新方法,用以取代传统的火法。该法使用电解返回的H_3SiF_6在常压下浸出混合硫化铅锌精矿,浸出温度为95℃。有86％的铅被选择浸出,89％的锌则留在浸 The U.S. Bureau of Mines has proposed a new method of treating mixed lead and zinc concentrates to replace the traditional fire method. The method uses electrolysis returned H_3SiF_6 leaching mixed lead sulfide zinc concentrate at normal pressure, the leaching temperature is 95 ℃. 86% of the lead is selected to leach, while 89% of the zinc remains in the dip
