  • Coking coal from South Africa, Russia & Mozambique

    Coking coal is transformed into coke by purifying it into almost pure carbon by heating bituminous coal in absence of oxygen to extremely high temperatures. Coke quality is largely influenced by the grade of coal, composition, mineral content and its ability to soften when heated, become plastic, and resolidify into a coherent mass.SOUTH AFRICAN COAL SECTOR REPORT Energy,usually classified as bituminous, occurring in seams up to several metres thick, while KwaZulu-Natal coal is often anthracitic and are found in relatively thin seams. The recoverable coal reserves in South Africa amount to some 66.7 billion tons, equivalent to about 7% of the world’s total (DMR, 2016).
