How Does Pulp Concentration And pH Affect Froth Flotation …

In froth flotation process, the pH value of the pulp needs to be paid close attention to at all times. The pH value needs to be measured with a test paper every once in a while to ensure that the pH value remains at a stable value. And the pulp concentration and liquid level need to be stable, ensure scraping, to scrape out the full plate.

Froth flotation

Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
