70 Purity Flotation Reagents Collectors In Froth Floatation Process

The role of the collector increases the hydrophobicity of its surface, and it has a certain degree of floatability. Even for natural hydrophobic minerals, for effective flotation, non-polar oil collectors should be appropriately added to improve their floatability. Packing: Plastic Drum

How Froth Flotation Works - Mine Engineer.Com

the process of froth flotation is generally described as a physical-chemical action, where a mineral particle is attracted to, and attaches itself to the surface of a bubble, and is transported to the surface of a cell, where it overflows into a discharge launder, usually with the assistance of paddles, rotating in the direction of the launder .
