FROTH FLOTATION

FLOTATION is a physico-chemical separation process that utilizes the difference in the surface properties of the valuable and gangue minerals. FROTH FLOTATION involves three different phases- solid (fine ore powder), liquid (water) and froth. The process of separation of mineral includes three important mechanisms : 1.

Flotation

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.

Mineral Processing

Mineral processing facilities are challenged with inherent problems. For example, the reagent scheme in a bulk Cu/Mo or Cu/Au/Mo flotation circuit may cause issues in downstream separation. Careful attention must be given to all reagents in the system. Any reagent or operational upstream change will also impact the downstream phase of production.
