particles even when flocculant molecules are used Combined with the fact that many flocculants do not bind to colloidal silica, there exists a second mechanism, the physical blocking of the flocculant polymer chains by silica particles that prevents them finding and bridging gangue particles.

Mar 23, 2013· · Particles of "locked" mineral and gangue are called middlings Degree of liberation is the %age of mineral occurring as free particles in the ore in relation to the total content. If there are weak boundaries between mineral and gangue then there will be high degree of liberation

Then air is passed through this mixture. This results in the agitation of water in tank, which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth. The gangue particles being heavier remain behind at the bottom of water tank. The froth is separated and concentrated sulphide ore is obtained from it.

the gold particles are liberated from the gangue particles. It is customary to use riffled sluiceboxes to recover the liberated gold particles. However, some of the gold particles, particularly the find gold, does not settle out in riffle compartments, and flow over to the discarded tailings. In the hope

Ore dressing. Comminution is a single or multistage process whereby ore is reduced from runofmine size to that size needed by the beneficiation process. The process is intended to produce individual particles which are either wholly mineral or wholly gangue, that is, to produce liberation.

The finer an ore is ground, the greater the energy that is required, so it makes sense to fine grind only those particles that need fine grinding. Complete liberation is not required for rougher flotation, only sufficient liberation to release enough gangue from the valuable mineral to get a high recovery.
