Coal mining played a supportive role as provider of energy to the growing gold mining industry and indeed, many collieries were historically and are today owned by gold mining companies. To these coal mine owners it was more important to keep the costs of their own energy inputs low, than to profit from coal mining itself4. The coal
· Mining wastes, • Tailings, and • Secondary processing wastes. Mining wastes, also known as extraction wastes, overburden or coal spoil (CS), are rocks and minerals generated from the mining and preparation plants resulting from opening up the main mineral deposit, composed mainly of cap and interlayer rocks.
Keywords: carbon capture and sequestration; mine waste management; reactive mine wastes 1.
