Jun 07, 2021 Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if ...
The amount of natural radionuclide present in environment, especially soils, sediment and water in the abundance tin mining area are varies depending on the amount of heavy minerals left over in that particular place. If the place used to be the processing area for tin ores, the left over known as amang contains heavy minerals.

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
