Copper Sulphide Ore

Copper Sulphide Ore from Pakistan

Copper sulphide ore is the primary source of copper metal worldwide. The dominant mineral in most copper sulphide deposits is chalcopyrite (CuFeS₂), often accompanied by bornite (Cu₅FeS₄), chalcocite (Cu₂S), and covellite (CuS). Pakistan’s copper deposits are part of the Tethyan metallogenic belt, the same geological formation that hosts major copper-gold deposits across Iran, Turkey, and Chile. Mining operations in Balochistan and Khyber Pakhtunkhwa extract copper sulphide ore for both domestic processing and export.

Available Forms

• Run-of-mine (ROM) lumps: 0–300 mm

• Crushed ore: 0–50 mm, 0–25 mm

• Hand-sorted high-grade lumps: 50–200 mm (15–25% Cu)

• Custom sizing available

Key Minerals

• Chalcopyrite (CuFeS₂) — primary copper mineral

• Bornite (Cu₅FeS₄) — secondary copper mineral

• Pyrite (FeS₂) — iron sulphide gangue

• Quartz (SiO₂) — silicate gangue

Industrial Uses

• Copper smelting: Direct feed to copper smelters (flash smelting, reverberatory furnace, or blast furnace) for production of copper matte and blister copper

• Flotation concentration: Beneficiation through froth flotation to produce copper concentrate (25–35% Cu) for smelter feed

• Hydrometallurgical processing: Leaching and solvent extraction/electrowinning (SX-EW) for copper cathode production from lower-grade ores

• Precious metals recovery: Gold and silver credits recovered as byproducts during copper smelting and refining

• Sulphuric acid production: SO₂ gas captured during smelting is converted to sulphuric acid as a co-product

• Copper chemicals: Processed copper used to manufacture copper sulphate, copper oxide, and other copper-based chemicals

Quality Assurance

Each lot includes a Certificate of Analysis reporting Cu, Fe, S, SiO₂, Au, Ag, As, Pb, Zn, moisture, and particle size distribution. Assays are performed by accredited laboratories. Pre-shipment samples are provided for buyer approval. Third-party inspection (SGS, Intertek, Alex Stewart, or equivalent) can be arranged. Umpire assay provisions are available for large contracts.
