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 removed, while ...

Alluvial Gold | Goldrush Mining

The technique of gold recovery from golden sands is known since ancient times, described by Plutarh, Strabon, Plinius and Diodor from Sicily. For this purpose, buddle ("saitroc"), woven sieves and burned clay boards were used. These boards were rounded, with a very good drainage opening, having on the inner bottom and on the side walls some ...
