一般铜电解精炼中电解脱铜防止酸雾,采用在电解液表面加皂根水的办法,但皂根水加入到电解液表面所起的泡沫气泡比较松,往往在循环速度稍大时,气泡很易破环:气体(AsH_3)易从疏松地方跑出,因此防止效率不大,并要经常加入(0.4竔/每平方公尺每4小时的皂根水),无形中增加电解液水份。每当脱铜完毕送往浓缩囘收无水硫酸镍时,就需化费大量的 Copper electrolysis in general electrolytic copper removal to prevent acid mist, the use of soap in the electrolyte solution of water on the surface, but the soap water to the surface of the electrolyte foam bubble is relatively loose, often slightly larger circulation speed, the bubble Very easy to break: gas (AsH_3) is easy to run from the loose place, so to prevent inefficient, and often to be added (0.4 竔 / square meter every 4 hours of soap root water), virtually increase the electrolyte water . Whenever the finished copper sent to the concentrated recovery of anhydrous nickel sulfate, the need to spend a lot of
