Froth Flotation Purdue University

2007-9-18  Froth Flotation. After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic. By adding a carbonated solution to the sample, we can separate up to 95% of the feldspar.

Froth Flotation for the 21st Century E & MJ

2020-4-8  Froth flotation has been a stalwart in mineral beneficiation for more than 100 years. During this time, and particularly in the past 20-30 years, there have been significant advances in the design and application of mechanical elements for flotation systems, e.g., new mechanisms, launders, larger cell volumes, better pumps, etc.

Kaolinite removal in iron ore flotation mainly involves three interactions, i.e. collector-kaolinite interactions, depressant -kaolinite interactions, and dispersant-kaolinite interactions.

A Brief Review of Pulp and Froth Rheology in Mineral

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
