Suppliers of lithopone ZnS-BaSO4 are committed to maintaining strict quality control measures throughout the manufacturing process. They ensure that the raw materials, zinc oxide and sulfur, as well as barium sulfate, are sourced from reliable suppliers to guarantee consistency in the final product. Advanced production techniques, such as precipitation and calcination, are employed to refine the pigment, ensuring its purity and uniform particle size distribution.

Factories specialized in barium sulfate production employ different techniques to refine the mineral. The most common method is the wet process, where barite is ground and mixed with water, allowing lighter impurities to float while the heavier barium sulfate sinks. After separation, the resulting slurry is dried and heated to obtain the final product. Some advanced factories also utilize flotation or magnetic separation methods to enhance purity.
