Research and application of fluidized flotation units: A review

In a study of fluidized bed flotation coal, Wang and Wang obtained a flotation product yield of 96.4% under moderate superficial gas rate conditions [76]; under high superficial gas rate conditions, the flotation product yield reached 99%, with all low-density particles becoming products. The superficial gas rate has some effect on the recovery ...

10 Problems in the Flotation Process and Troubleshooting

(1) Affect the recovery rate. When the pulp density is small, the recovery rate is low; when the pulp density increases, the recovery rate increases. But the recovery rate exceeds the limit, the recovery rate will decrease, as the too high density will destroy the aeration conditions of the flotation machine. (2) Affect the concentrate quality.

Gold Extraction & Recovery Processes

Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

Flotation Machines: High-Performance Equipment for Mineral Recovery

Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means water loving and …
