A fresh approach to sulfide ores - CIM

T he copper mining industry is reaching a turning point. Surface oxide deposits are depleting and copper miners are turning their attention to untapped sulfide ores found deeper underground. However, sulfides require more expensive processing techniques since they are not responsive to standard technologies that are used in oxide heap leaching.

Process of Sulfide Mining. The method of sulfide mining is broken down into five steps: : Exploration Development Mining Smelting and Refining and reclamation. Exploration has mostly of testing the site to find if the source of the minerals is more enough to make mining the site valuable. Extensive core drilling and metallurgical mass sampling are the major tests that a concern will do during exploration.

Sulfide Mining | Sierra Club

The mining of copper/nickel sulfide ores is a toxic type of mining that is risky to our environment, our workers and communities, and local economies. Mining sulfide rock releases acid and toxic metals and contaminants that pollute rivers and groundwater for hundreds of years, long after the profits are spent and theuried in landfills.

The Threat of Sulfide Mining Friends of the Boundary Waters ...

What is copper-sulfide mining? Sulfide mining, which is sometimes referred to as hard-rock mining, is the process of extracting trace amounts of copper, nickel and other metals from sulfide ores. When sulfide ore comes into contact with water or oxygen, a chemical reaction occurs and produces sulfuric acid, which is the same as battery acid.

Copper Sulfide Mining - Earthworks

Copper Sulfide Mining. Copper Sulfide Mining. A peer-reviewed study of the track record of water quality impacts from copper sulfide mines found severe impacts to drinking water aquifers, contamination of farmland, contamination and loss of fish and wildlife and their habitat, and risks to public health. In some cases, water quality impacts were so severe that acid mine drainage at the mine site will generate water pollution in perpetuity.

What is Sulfide Mining? | Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created threatening to poison the nearby water, environment, and communities.
