Governmental legislation on prohibiting toxic materials and prevention and control of the volume of waste has helped in decreasing adverse environmental effects. There is a growing public awareness about waste prevention and its beneficial effects. The society has to replace the linear model of extract-produce-consume-dispose to closed Loop's approach of resource recovery and waste ...

Extraction Stage

Extraction of copper produces both specks of dust and gaseous wastes such as sulfur dioxide and carbon dioxide that significantly contribute to environmental pollutions, especially air pollution (“Copper Mining”). Whereas copper wire miners reduce this pollution level by trapping the generated sulfur dioxide gas for purposes of producing sulfuric acid, considerable amounts of sulfur dioxide still escape and take part in both air and water pollution. However, extraction methods that incorporate emulsion of liquid membranes and applications of microorganisms in removing copper from their underground ores have been currently established as the economical and viable ways of gathering copper. ...
