Phosphate Flotation Mineral Processing & Metallurgy

The complete removal of slimes is essential to successful phosphate flotation. The cyclone classifier overflow is partially deslimed and densified using a Spiral Classifier. The deslimed sands at uniform density from the spiral classifier are subjected to attrition scrubbing at approximately 60-70% solids to thoroughly clean the mineral particles of slime producing material. A 4-cell

Recovery of Phosphate Minerals from Plant Tailings Using

Direct flotation is generally used to process phosphate ores that are rich in silica and dolomite minerals. The grade of P2O5 can be increased up to ~30%–34% in concentrate products at above 80% recovery [20]. A direct flotation process of phosphates has been used by Florida’s phosphate mines for a long time. In this process, fatty acids

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, stone 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. It has been described as "the single most important operation used for the

Beneficiation of Ultrafine Cassiterite from a Tin Tailings

A flotation process has been used on a laboratory scale to investigate the effects of various reagents such as salicylhydroxamic acid, lead nitrate, sodium hexametaphosphate and pine oil on tin recovery at neutral pulp. Because cassiterite is friable and a large amount of fines and slimes were generated, usually de-sliming is used to prevent slime coating and to increase the recovery of tin
