Exposed: Firms sell toxic mine dump sand to unsuspecting building industry
Sand tailings at Snake Park in Soweto, 10 June 2019. Mine dumps are made up of crushed, sand-like by-product refuse material, known as tailings, produced during the mining process. Mine dumps are made up of a complex mixture of metals and dust particles. Dust exposure can be high for communities living nearby, particularly during windy conditions and when it’s dry and vegetation cover is low.Picture: Nigel Sibanda
When the sand is mixed with cement and water, it releases radon gas, which is the second-biggest cause of lung cancer.
