How to Solve the Common Problems of Froth

As the common mineral processing process, the froth flotation process is widely used in the concentrator. Because the froth flotation process is strict with grinding fineness, pulp density, flotation reagent, the flotation plant operators must inspect the flotation conditions during the operation of the flotation machine.

Seven Common Froth Flotation Processes - Xinhai

6. Flash flotation process. Flash flotation process is a process that adds the single-trough flotation in the grinding circuit. Before the conventional flotation process, the flash flotation process can be used to pre-float a part of qualified concentrate, which reduces the loss caused by overgrinding of useful minerals.
