Experimental Study on the Preparation of Supernatant from Secondary Zinc-containing Materials by Total Wet Method
As a zinc smelting enterprise,in order to get rid of dependence on the increasingly scarce zinc sulfide concentrate raw materials,the secondary zinc-containing materials to replace part of the zinc sulfide concentrate raw materials was studied producting the supernatant.Three-stage leaching(medium-acid-high)was used to remove Cl,Fe,F in onder to prepare qualified supernatant.This fully wet process is simple,less investment and low energy consumption,which provides technical support for the utilization of secondary zinc-containing materials in our company,and also provides new ideas for the reuse of secondary zinc-containing materials in the industry.
