Cement-Grade Gypsum from Pakistan
Pakistan has some of Asia’s largest sedimentary gypsum deposits, primarily in the Salt Range region extending across the Punjab and Khyber Pakhtunkhwa provinces. Raw gypsum is mined and crushed on-site, then supplied to local cement plants and exported to cement manufacturers worldwide.
Typical Composition
CaSO₄·2H₂O: 90–95%, SO₃: 43–45%, SiO₂: ≤ 2%, Fe₂O₃: ≤ 0.5%, MgO: ≤ 0.5%, Moisture: ≤ 2%
Available Sizing
0–6 mm, 0–10 mm, 0–50 mm, or crushed to the sizing required by your cement plant
Quality Verification
Each lot includes a Certificate of Analysis. Pre-shipment samples are sent for approval before dispatch. Third-party inspection (SGS or equivalent) can be arranged on request.
