Copper production & environmental impact GreenSpec

Tailings are a slurry of fine grained rock material and process water. Liquid is removed from the tailings slurry in thickeners and the thickened tailings are discharged to the tailings impoundment. Water is usually reclaimed from the thickeners and recirculated to the mill to be used in beneficiation and dust control (Mining.

Production of gold has many negative environmental effects

Sep 21, 2010 . Whether or not they roast the ore, big mining operations typically finish off the extraction process by dousing the ore in cyanide. Cyanide is extremely lethal, but as an environmental contaminant it's not as problematic as mercury, since it degrades fairly quickly. (Mercury sticks around forever.) Some of the.

Environmental Impacts of Metal Ore Mining and Processing: A Review

The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment. Copper.
