The aim of a mineral processing operation is to concentrate a raw ore for the subsequent mineral extraction stage. Usually, the valuable minerals are first liberated from the ore matrix by comminution and size separation processes (crushing, grinding, and size classification) and then separated from the gangue using processes capable of selecting …

preconcentration underground in a narrow-vein mining situation. These include: • Reduction in total comminution energy requirements (lower carbon footprint) as some of the waste is removed at a coarser size early in the process route. • Reduction in tramming and hauling costs both underground and prior to surface processing, due to lower
