Mine Waste

Mining generates a range of waste streams in its mineralised waste. The bulk of these are residues consisting of waste rock and tailings. Other residues, produced in smaller volumes, include concentrated effluents, sludges, sediments, leached are residues, slags, furnace dust and filter cakes.

As one of the largest contributors to national waste, South African mines should be rethinking their usual linear approach to managing residues. Beyond improving their environmental and social impact, they may be surpriced by the economic benefits.
