1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

Recovery of valuable metals from WPCB fines by …

In the flotation process, an increase was observed in the amount of rejectable tailing due to further liberation of the waste matrix. Although the metallic values escaping to the tailing are quite low, centrifugal gravity separation and/or scavenging flotation processes can be subjected to recover noble metals with higher economic value.
