The mining industry is a diverse collection of sciences, techniques, methods, and operations that, by specifying the grade and type of the mineral; and based on various methods, enrich the identified mineral, the result of which it can be used as a raw material in the production of various products in the intermediate industries

The main activities of this field include assessing the chemical and mineralogical composition of minerals, mineral processing (crushing, milling, flotation, gravity separation, magnetic separation, etc.), and extractive metallurgy (dissolution, solvent extraction, electrowinning, etc.).
