Chemical products
Sulfuric acid
PPC supplies sulfuric acid produced in the smelting processes from sulfur contained in copper concentrate.
It is a colorless, odorless viscous liquid, and multiple type of products are available for different uses, which range widely from industry to agriculture.
Brand and specification
| Sulfuric Acid Content | Residue on Ignition | Iron Content | |
|---|---|---|---|
| Concentrated Sulfuric Acid | Nominal sulfuric acid or more | 0.05% or less | 0.03% or less |
| Dilute Sulfuric Acid | |||
| Oleum | Nominal free sulfur anhydride or more |
Applications
Fertilizer, textile, paper and pulp, titanium oxide, resin, steel
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.
