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.

The objective of mineral processing is to render mineral resources beneficial to the modern life of the humankind. Mineral resources occur as a textual intergrowth of various mineral components, and as extracted from the ore body, they are not useful as they are.

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.
