試驗是在正規的大型鉛襯鋼筋混凝土槽內进行的。电解溶液容积是12个多公尺~3,槽內有盤形的鉛管間接加热,有圓形的鉛管通风攪拌。試驗采用条件:电解液中銅离子濃度40～45克/立升;游离硫酸190～200克/立升;鎳离子濃度10～14克/立升;砷离子濃度3～4克/立升;銻离子濃度小于1克/立升;铁离子濃度小于1克/立升;比重1.22～1.24。首先电解液經过沉降电解液中悬浮的泥渣沉淀保持溶液清洁,一般每1公尺~3溶液沉降半小时,(特殊情况例外)。然后打入中和槽內,加热溫度保持在80～90℃,攪拌风每分鐘0.5公尺~3,蒸
The test was carried out in a regular large-scale lined reinforced concrete tank. Electrolytic solution volume is more than 12 meters ~ 3, the tank has a tray-shaped indirect heating pipe, a circular lead pipe ventilation. Test conditions: the concentration of copper ions in the electrolyte of 40 to 45 g / liter; free sulfuric acid 190 to 200 g / liter; nickel ion concentration of 10 to 14 g / liter; arsenic ion concentration of 3 to 4 g / Antimony ion concentration of less than 1 g / 立 升; Iron ion concentration of less than 1 g / 立 升; Specific gravity 1.22 ~ 1.24. First of all, the electrolyte is kept in solution by sediment suspension suspended in the settling electrolyte, usually settling for half an hour per 1 meter ~ 3 of solution, with the exception of special cases. Then into the neutralization tank, the heating temperature is maintained at 80 ~ 90 ℃, mixing wind 0.5 meters per minute ~ 3, steaming
