Mention the three main process of mineral extraction

Aug 17, 2021

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
