impact flotation process for mineral production

Introduction to Mineral Processing Chevron Phillips Chemical

Frothers are liquids that produce the froth or foam on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be.

Clay Minerals in Flotation and Comminution Operations

Aug 30, 2017 . The soft nature of these minerals induces the production of a large amount of slimes. The presence of slimes has a negative impact on slurry rheology, with detrimental effects on both flotation and comminution. The presence of fine hydrophilic slimes also causes slime coatings and high amounts of.

Effect of froth stability on dewatering of coal flotation concentrates .

The results show that high froth stability originating from a flotation process has a negative impact on the filtration and dewatering of flotation concentrates. In this study, the flotation of fine coal using saline water produced a highly stable froth with a high air recovery resulting in a short cake formation time and a high final.
