New applications of deep eutectic solvents for separation

Jan 01, 2021· A aliquat 336/lactic acid deep eutectic solvent was used for the reverse flotation of magnetite for the first time. The deep eutectic solvent increased the total iron content of the feed ore from 53.02% to 66.80%, which was better than dodecylamine.

Flotation of Iron Ore: A Brief Review MDPI

Fatty acids are widely used as a collector in the reverse anionic flotation of iron ores. The most popular anionic collectors used in iron ore flotation practice are oleic acid and its soaps [16,26]. The oleate in aqueous solution forms different species and which species dominate is dependent on pH.

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.

In addition, the process can be used to extract copper in situ. That is, without removing the material from the waste pile or from the ground. The net result of the use of this process is that copper can be produced from sources that in the past would have gone untouched, thus reducing the reliance on conventional ore bodies.

Magnetic Separation: Minerals can be separated on the basis of differences in magnetic susceptibility. Magnetic separation has been used in Canada to separate iron ore from waste minerals, to remove magnetite (iron oxide) and pyrrhotite (iron sulphide) from base metal ores prior to flotation, and to recover magnetite from copper concentrates.

Iron Ore Concentration Process Magnetite is mined in large chunks and is crushed into small particles by a series of crushers. After primary crushing with jaw crushers and secondary crushing with gyratory crushers and tertiary crushing with cone or high pressure grinding rolls (HPGR), the ore is screened on vibrating screens to size the particles.
