Iron Ore Mining Water Pollution

Iron Ore Mining Water Pollution

In terms of mining pollution prevention is the maximum feasible reduction of the quantity and or toxicity of all wastes generated at a mining operation It involves the judicious use of resources through source reduction energy efficiency reuse of input materials during production and beneficiation and reduced water consumptionOther environmental problems may be associated with mental mining and beneficiation Another type of water contamination is waste water from beneficiation plants which may contain ore material heavy metals thiosalts and chemical reagents used in beneficiation Air pollution is
