Extraction is the removal of the ore from the earth. Beneficiation follows extraction and involves working the ore into a more useable form. Finally, mineral processing removes the desired mineral from the remaining ore. The extraction and beneficiation processes produce large quantities of waste; however, the mineral processing phase generally ...

Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other ...
