Froth flotation - Wikipedia

Froth flotation is a process for selectively separating of 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.


The froth flotation process mainly includes grinding, slurry adding, froth flotation separation and dehydration of products and tailing products after froth flotation. Before the flotation operation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.

A novel method of cryogenic grinding and froth flotation is proposed to recover LiCoO 2 and graphite from spent lithium-ion batteries. After 9 min of cryogenic grinding, the grade of LiCoO 2 concentrate was up to 91.75%, with a recovery rate of 89.83% after flotation, but the materials that have not been cryogenic grinding, the grade and recovery rate of LiCoO2 after flotation only 55.36% and ...


The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.


The froth flotation process mainly includes grinding, slurry adding, froth flotation separation and dehydration of products and tailing products after froth flotation. Before the flotation operation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.


Froth Flotation machine plays an indispensable role in the mineral beneficiation process, flotation is susceptible to a number of factors during the process, including grinding fineness, slurry concentration, pulp pH, pharmaceutical system, aeration and agitation, flotation time, water quality and other process factors. The factors that affect ...

Froth flotation is the main ore concentration method for recovery of fine particles, i.e. particles −100 m [7,8]. ... The effect of dry and wet grinding on the flotation of complex sulfide ores ...


Therefore, the grinding fineness of the grinding mill must meet the following requirements before the froth flotation: The useful minerals are liberated; The granule degree of coarse monomer ore must be lower than the upper limit of particle size of mineral flotation (the vulcanized mineral is generally 0.25-0.3mm, the natural sulfur is 0.5-1mm);


grinding practice in the mills tends to leave the siegenite as binary locked particles in the various product streams (fig. 1). Therefore, further grinding to liberate the siegenite particles is required, but is limited by the lower size limita­ tions of the froth flotation and by grinding energy considerations.


Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. ... which increases the selectivity of separation in flotation, but raises grinding costs and ...
