2) Purification: Add ammonium persulfate to the final immersion solution for one-time oxidation and iron removal, and add activated carbon to adsorb arsenic and iron co-precipitation to achieve the purpose of removing arsenic. Add the polyacrylamide coagulant to separate and filter before separation. The sulfide solution is added to the solution to remove sulfur, and the separated filtrate obtained by the separation is replaced with zinc powder to remove the remaining impurities to obtain a zinc sulfate ammonia complex liquid, which is used in the next step;

Lithopone, a white pigment composed of a mixture of zinc sulfide and barium sulfate, has become an indispensable ingredient in the paint industry. Its unique properties, including excellent opacity, high brightness, and resistance to weathering, make it highly valued among paint manufacturers. As the demand for sustainable and efficient paint products grows, the role of lithopone and its suppliers has become more critical than ever.
