Mineral Processing Froth Flotation

2015-6-22  Mineral Processing Froth Flotation. Froth Flotation is a mineral processing process achieving solid-solid separation by taking profit of the chemical attribute leading to the possibility of selectively controlling the relative surface hydrophobicities of the various components mixed in an aqueous medium. Froth flotation

Flotation Froth - an overview ScienceDirect Topics

The use of froth in flotation is twofold. Firstly, froth is used to convey the mineral laden bubbles from the froth-pulp interface to the concentrate launder. Secondly, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by applying spraying (wash) water upon the surface or inside the upper layer of the froth.

TECHNICAL NOTES 9 FLOTATION - mineraltech

2009-7-30  The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth. The bubbles do not burst when they cross the interface and each one carries a skin of water into the froth phase.
