Products — Metallurgical coal
Metallurgical (coking) coal supplier for Africa
Zimbabwe's Hwange basin produces genuine coking coal with low ash and low sulphur — a scarce commodity on the continent. We supply steel mills, ferro-alloy and ferro-chrome smelters, foundries and coke producers across Africa.
Coking properties are certified per consignment, so your blend engineers get the fluidity, CSR and volatile matter data they need before the coal ships.
Typical coking coal specification
Our metallurgical grade averages 7,200 kcal/kg with ash at or below 10% and sulphur at or below 0.8%. Full proximate and ultimate analysis, plus coking indices, are supplied with every certificate.
Who buys metallurgical coal from us
Integrated and mini steel mills, ferro-chrome and ferro-manganese smelters, iron foundries, coke batteries and calcining plants across South Africa, Zambia, the DRC, Mozambique and international markets.
Contract supply and blending
Long-term offtake agreements with agreed price review formulas are available. Where a single seam does not meet your blend requirement, we blend to specification and certify against the contract table rather than against a nominal grade.

Frequently asked questions
- Is Zimbabwean coal suitable for coke making?
- Yes — Hwange coking coal has low ash and low sulphur and is used in operating coke batteries in the region.
- Do you supply coking indices with your analysis?
- Yes. Certificates include proximate and ultimate analysis and coking indices such as FSI and volatile matter.
