Froth flotation - Wikipedia

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

A novel method to improve carboxymethyl cellulose ...

Jan 15, 2019· A novel method to improve carboxymethyl cellulose (CMC) performance in talc flotation is described in this paper. Micro-flotation results showed that using CMC as the depressant, strong depression on talc floatability was observed when the pulp pH was adjusted from low (4.0) to high (8.5), which improved the separation performance between chalcopyrite and talc.

Talc Beneficiation Process - Flotation

Talc: Part of 19 "Sub-A" Flotation Cells floating talc. Result: A concentrate approximately 94% talc produced at the rate of ¾ tons per hour. Flotation produces a uniformly pure product at a low cost per ton of ore processed and in addition recovers talc which cannot normally be recovered by dry processes.

Then the second step involves the alteration of serpentine to form talc. The rocks have talc, chlorite, magnesite, sulfides and many different minerals having very low content of quartz in them. In this process, crude ore is grinded and crushed before the refining is done by flotation so that the content of talc …

that is hydrophilic. On the other hand, the rupture of talc crystals along the faces generates non-polar surfaces, which are characterized by a low energy (El-Midany and Ibrahim, 2010 [5]; Mierczynska and Beattie, 2013 [6]). This allows talc to exhibit an inherent hydrophobicity, which is the basis of the separation of talc, by flotation,
