Mineral Extraction an overview ScienceDirect Topics

Mineral extraction (mining) and petroleum and gas production are major resource extraction activities that provide the raw materials to support our economic infrastructure. An enormous amount of pollution is generated from the extraction and use of natural resources. The Environmental Protection Agency’s Toxic Releases Inventory report lists mining as the single largest source of toxic waste

Selective Extraction Chemistry of Toxic Metal Sulfides

Experimental evidence suggests that formation of metal sulfides in anoxic sediments limits the bioavailability of several toxic elements. Our ability to quantify the processes by which these metal sulfides form is dependent upon our ability to determine the speciation of solid phase metals in sediments. Our work indicates that an entire suite of Cu-Fe and Ni-Fe sulfide minerals can form upon

Sulfide Minerals an overview ScienceDirect Topics

The types of mines that are responsible for highly acid water and toxic levels of trace metals include all mines that contain metal sulfides (e.g., iron, lead, zinc, copper). Therefore, mines that extract aluminum, coal, copper, gold, lead, silver, and zinc will usually pollute surface and groundwater resources with acid and toxic metals.
