工業硫酸鋅廠家利用銅(tong)(tong)渣中(zhong)含有的(de)(de)(de)單質(zhi)銅(tong)(tong)、銅(tong)(tong)渣氧(yang)化(hua)產生(sheng)(sheng)的(de)(de)(de)Cu和溶(rong)液中(zhong)的(de)(de)(de)氯離(li)子(zi)反(fan)應產生(sheng)(sheng)難溶(rong)的(de)(de)(de)CuCl沉(chen)淀，撤除硫(liu)酸鋅(xin)(xin)溶(rong)液中(zhong)的(de)(de)(de)氯。此發明能將濕法煉(lian)鋅(xin)(xin)過(guo)程中(zhong)產生(sheng)(sheng)的(de)(de)(de)銅(tong)(tong)渣進(jin)(jin)一步利用，先將銅(tong)(tong)渣中(zhong)的(de)(de)(de)片面單質(zhi)銅(tong)(tong)氧(yang)化(hua)得到(dao)Cu離(li)子(zi)，無(wu)需進(jin)(jin)入硫(liu)酸銅(tong)(tong)即可得到(dao)Cu離(li)子(zi)，達到(dao)同時供應單質(zhi)銅(tong)(tong)和Cu離(li)子(zi)介入除氯反(fan)應的(de)(de)(de)效(xiao)果，這(zhe)樣在除氯過(guo)程中(zhong)就不需要進(jin)(jin)入硫(liu)酸銅(tong)(tong)，使銅(tong)(tong)渣得以充(chong)分利用，降低了(le)生(sheng)(sheng)產老本，簡化(hua)了(le)操作程序(xu)，不增長(chang)廢(fei)渣、廢(fei)氣、廢(fei)水(shui)排放，無(wu)環境污染(ran)，所花(hua)消的(de)(de)(de)質(zhi)料(liao)為(wei)普通質(zhi)料(liao)，且花(hua)消量較少，經濟(ji)效(xiao)益(yi)顯著。
