Mineral Processing Introduction - Met-Solve Laboratories Inc.

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate.

The role of gravity concentration in modern processing plants .

That such an ancient and inherently simple process has not only survived, but thrived, is in part due to its very simplicity. Not only is gravity concentration the process of choice in small, remote, artisanal plants, it also continues to play a major role in larger, “modern” plants for the concentration of many minerals, literally from.
