Mining Industry Profile | Department of Energy

The mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks. Oil and natural gas extraction (NAICS code 211) is not included in this industry.

Froth Flotation Process Mineral Processing Metallurgy

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (waterrepel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
