Depressants In Froth Flotation

2019-10-24ENHANCED PHOSPHATE FLOTATION USING NOVEL DEPRESSANTS . Froth flotation is the most efficient method for phosphate separation, which is a physic-chemical separation process based on the difference of surface properties between the valuable minerals and unwanted gangue minerals. However, the presence of clay.

    ROLE OF DEPRESSENT IN FROTH FLOATATION

    Depressants prevent certain type of particles from forming froth during froth floatation process. A common depressant used in the froth floatation of lead sulphide is sodium cyanide. When the ore containing ZnS and PbS is subjected to froth floatation process in the presence of NaCN, then only PbS forms the froth.
