Flocculation - Wikipedia

Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent.The action differs from precipitation in that, prior to flocculation, colloids are merely suspended, under the form of a stable dispersion, in a liquid and are not truly dissolved Term definition& 0183;& 32;

Flocculation - Aquatec Maxcon

Flocculation begins immediately following particle destabilisation in the preceding coagulation stage. Often, flocculation aid s are used to assist in forming denser floc particles. The process requires appli ion of gentle low-shear mixing equipment to enhance contact of destabilised particles and to build floc particles of optimum size, density and strength.

Froth flotation - Wikipedia

In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical although some mineral surfaces are naturally hydrophobic, 21 requiring little or no History& 0183;& 32;

Flocculation Test Procedure - Mineral Processing and …

A Flocculation Test Procedure is used to determine how much Flocculants need be added to solids in suspension slurry or pulp to cause the individual particles to collect in the form of flocs. The formation of flocs aids in improved settling rates, better overhead clarity and/or faster filtration rates. There are three main methods for achieving aggregation of very small or colloidal
