Froth Flotation Process

Apr 06, 2020· In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out.

Concentration Of Ore Definition Types And Properties Of Ore

Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allows it to form a froth.

Name Three Ores Which Are Concentrated By Froth

The three ores which are concentrated by froth-floatation process are: (i) Copper pyrites (CuFeS2)(ii) Zinc Sulphide (ZnS) (iii) Silver glance (Ag2S).Depressants are used to prevent certain types of particles from forming the froth with bubbles.Example: NaCN is used as a depressant in the separation of ZnS and PbS ore. NaCN forms a layer of Zinc complex Na2 Zn(CN)4 on the surface of ZnS and ...
