Some hazardous appearances in flotation tailings dumps in domestic mines

Abstract

Dangerous and hazardous flotation tailings dams can be source of endangering of living environment. In their normal work and also in case of damages incidents in flotation tailings dams can be caused by natural catastrophe in the area or malfunctions due to unreliable work. Harmful chemicals, which can get to living environment at damages, can cause endangering of ecological factors (soils, water, air) and through them the whole ecosystem of the area. The paper describes the incidents on the tailings dams of the nonferrous mine in the Republic of Macedonia.

Application of Copper Mining Waste in Radionuclide and Heavy Metal Immobilization

“…The reuse of copper slag is increased worldwide, and a considerable amount of CSFT is disposed of. Generated and accumulated CSFT represents a possible environmental threat, potentially polluting watercourses by atmospheric precipitation, wind erosion, or accidents, [7][8] e.g., dam rupture and spilling pollutants into underground water systems. [9] Although CSFT represents the end waste, with a matrix composed of iron silicates, it could be utilized as a raw material in construction industry and metallurgy, providing environmental and economic benefits.…”
