Zinc Sulfide Concentrate

There are two major types of Zinc Sulfide Concentrate — natural sphalerite concentrate and synthetic ZnS pigment-grade. Each is carefully produced to meet the requirements of different industries such as metallurgy, ceramics, rubber, plastics, and phosphor manufacturing. During production, zinc-bearing ores undergo crushing, grinding, and selective flotation to achieve a high ZnS concentration, typically ranging between 55% and 65%. The product is dried, screened, and tested to ensure consistent particle size and purity. Zinc Sulfide serves as an essential raw material for zinc extraction in smelters, a luminescent material in optical devices, and a pigment base in coatings and ceramics due to its superior whiteness and brightness.
