New liquid ingredient: Zn 140g/l, Cu 0.1mg/l, Cd 0.8mg/l, Co 0.7mg/l, Si 31.38mg/l, Ge
0.08mg/l, As 0.1mg/l, TOC 158.3mg/l.
Deep purifying is carried out to solution of zinc sulfate using Tthe utility model system, handles 1m3Zinc powder 6.09kg is needed, and is used
Conventional system purifying zinc sulfate solution handles 1m3Need zinc powder 7.5kg, it is therefore apparent that the utility model, which has, utilizes reduction zinc powder list
Consumption, while unconventional elements Si and organic matter can be removed, it is relatively good compared to conventional purge procedures clarity of solution, and two
Cobalt will not return molten (two sections of purified cobalts of conventional purge procedures easily return molten) after section purification, can guarantee that electrowinning process smoothly produces.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
