  • Froth flotationWikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

    Mar 01, 20211. Introduction. Froth flotation is the largest tonnage separation in mineral processing by which valuable mineral is separated from waste rock. Advances in control and optimisation of the froth flotation process are of great relevance since even very small increases in recovery lead to large economic benefits Ferreira and Loveday, 2000, Maldonado et al., 2007.

    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.
