工業硫酸鋅廠家利(li)用銅(tong)(tong)渣(zha)中(zhong)(zhong)含有的(de)(de)(de)單(dan)質(zhi)銅(tong)(tong)、銅(tong)(tong)渣(zha)氧化(hua)產(chan)生(sheng)(sheng)的(de)(de)(de)Cu和(he)溶(rong)液中(zhong)(zhong)的(de)(de)(de)氯(lv)離子(zi)反應(ying)產(chan)生(sheng)(sheng)難溶(rong)的(de)(de)(de)CuCl沉淀，撤除(chu)硫酸鋅溶(rong)液中(zhong)(zhong)的(de)(de)(de)氯(lv)。此發明能將濕法煉鋅過程中(zhong)(zhong)產(chan)生(sheng)(sheng)的(de)(de)(de)銅(tong)(tong)渣(zha)進一(yi)步利(li)用，先將銅(tong)(tong)渣(zha)中(zhong)(zhong)的(de)(de)(de)片面單(dan)質(zhi)銅(tong)(tong)氧化(hua)得(de)到(dao)(dao)Cu離子(zi)，無需進入硫酸銅(tong)(tong)即可得(de)到(dao)(dao)Cu離子(zi)，達到(dao)(dao)同(tong)時供應(ying)單(dan)質(zhi)銅(tong)(tong)和(he)Cu離子(zi)介入除(chu)氯(lv)反應(ying)的(de)(de)(de)效(xiao)果，這樣在(zai)除(chu)氯(lv)過程中(zhong)(zhong)就(jiu)不(bu)需要進入硫酸銅(tong)(tong)，使銅(tong)(tong)渣(zha)得(de)以充分利(li)用，降低了生(sheng)(sheng)產(chan)老本，簡化(hua)了操作程序，不(bu)增長(chang)廢(fei)渣(zha)、廢(fei)氣、廢(fei)水排放，無環境污染(ran)，所(suo)花(hua)(hua)消的(de)(de)(de)質(zhi)料為普通質(zhi)料，且花(hua)(hua)消量較少，經濟效(xiao)益顯著(zhu)。
