Background for NEPA Reviewers Non-Coal Mining Operations

Beneficiation procedures are used to increase the percentage of the desired mineral in the concentrate by separating the metal-bearing minerals from the non-valuable gangue (tailings). The separation is based on one or more differences between the mineral and the rest of the mined material, such as density or chemical nature.
