Abstract

The content of nickel in the lixivium of scrap copper smelting slag reaches 640mg/l while the zinc content is more than 100g/l. This high content of nickel in the solution must not only be separated from the leachate for resource recovery, but also for the subsequent zinc electrowinning which need to keep the nickel content less than 1mg/l to make the electrowinning process carrying out regularly. The lixivium was pretreated by zinc powder and most of the copper and cadmium was precipitated and the nickel content was reduced to 8mg/l. Then the antimony salt method was used to separate the remanent nickel. After a series of experiment, the nickel was reduced to 0.9mg/l to meet the zinc electrowinning standard under the best condition at 95 , 350r/min stirring speed, 10g/l of zinc powder, 6mg/l of Sb2O3 and 60min of reaction time. The removed nickel will be refined by further metallurgic method.
