美国矿务局研究了一个方法用锌阴极代替一般电积中使用的铝阴极。使用锌阴极就取消了剥片操作而且能够从含有过量氟化物的溶液中进行电积。试验采用了含有氟化物的锌精矿,按常规熔烧、浸出、净化。净化采用两段,净化前加入1.96克/升 The U.S. Bureau of Mines has investigated a method that uses a zinc cathode instead of the aluminum cathode used in a typical electrodeposition. Using a zinc cathode eliminates the delamination operation and enables electrodeposition from a solution containing excess fluoride. Test using a zinc concentrate containing fluoride, according to conventional melting, leaching, purification. Purification using two, before adding 1.96 g / liter purification
