Introduction to Mineral Processing or Beneficiation
Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals. 1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility.
Spiral (Concentrators)
For processing of sand minerals normally spirals are being used at onshore where the bottom or base of the plant remain stable and, the heavy minerals (grains with specific gravity generally greater than about 2.9) migrate to the inside of the spiral while the lighter materials (shell, quartz, phosphate, etc.) will be carried in the water stream toward the …
