Separation in mineral processing - Minerallurgy

The adsorption or not of water on the surface of mineral particles is exploited to achieve separation between valuable minerals and gangue. This separation technique is named froth flotation, and it is widely used for almost all types of ores. For this process, the material ground into a fine powder is mixed with water and chemicals. The addition of air form a froth on the surface of the suspension, in which …

Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated …

Mineral processing | metallurgy | Britannica

A successful separation of a valuable mineral from its ore can be determined by heavy-liquid testing, in which a single-sized fraction of a ground ore is suspended in a liquid of high specific gravity. Particles of less density than the liquid remain afloat, while denser particles sink. Several different fractions of particles with the same density (and, hence, similar composition) can be produced, and the valuable …
