  • The manufacturing process of lithopone involves several steps, including sulfide precipitation, grinding, classification, and packaging. During the sulfide precipitation stage, zinc sulfide and barium sulfate are reacted in an aqueous solution under controlled conditions to form a precipitate of lithopone. The precipitate is then washed, dried, and ground to the desired particle size distribution. Finally, the ground pigment is classified to remove any oversized or undersized particles and packaged for storage and transportation.
