Photo: Copper Slag

PPC supplies copper slag, iron silicate resulting from the bonding of iron in copper concentrate with silica in the copper smelting process. It is crushed by high-pressure water to form black, glassy granules.
Having a large specific gravity of 3.5 and high hardness (6 Mohs or more), this industrial product has greater grain size stability than natural sand.

Brand, shape, and size, etc. Copper Slag
Specification Composition: Fe 35 to 45%、SiO2 30 to 40%、Al2O3 3 to 5%
Grain size: 0.3 to 5mm
Applications Raw material for cement (Clinker iron source), sandblasting material Port applications (Caisson filling material, sand compaction material) Concrete products, and fine aggregate for ready-mix concrete

Copper Sulfate

PPC supplies copper sulfate which is produced by refining and crystallizing copper electrolyte in the copper refining process.
The product has a wide range of applications from agricultural chemicals to plating and catalysts.

Shape Blue crystalline powder
Quality specification CuSO4・5H2O≧98.5%
Main applications For agricultural chemicals (for disease control), industrial plating, catalysts



PPC supplies gypsum, a white powdered substance, which is produced by adding calcium carbonate to sulfur contained in copper concentrate.
Three types of gypsum are available depending on the production process.

Brand, shape, and size, etc Sulfuric acid gypsum, Flue gas desulfurization gypsum, and Acid effluent treatment process gypsum
Applications Gypsum board, raw material for cement (solidification accelerator)
