froth flotation cell for mineral separation

METHOD OF MINERAL SEPARATION BY FROTH

This invention relates to an improved process of mineral separation by froth flotation. In particular, it relates to a froth floatation. In particular, it relates to a froth flotation process in which much less power is used than has previously been the practice in processes having a comparable treatment capacity.

1 Froth Flotation – Fundamental Principles

2009-8-27  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
