Mineral processing - Concentration | Britannica

Flotation separation Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents.

Review of flotation of feldspar: Mineral Processing and ...

The general circuit for commercial separation of feldspar consists of three sequential stages of flotation, all of which are carried out in an acid medium. Usually, before flotation, the feed is deslimed, removing any fine clay minerals present. In the first flotation stage, mica is removed with an amine collector.

Foam flotation separation of dispersoids such as colloids and high molecular weight compounds in dispersions is carried out by drawing the dispersion into a pump which then passes it, as motive fluid, through a venturi to draw in air and effect an air emulsion-type mixture. Thereafter, the mixture passes into a separation column wherein the very small air bubbles in the emulsion are allowed to ...

Froth flotation circuit design and basic testwork requirements. In the flotation process, ore is ground to a size sufficient to adequately liberate desired minerals from waste rock (gangue); it is conditioned as a slurry using specific chemicals, generically referred to as 'collectors', that adsorb to the surfaces of the desired minerals.

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals) up to be recovered.

Jun 17, 2019 · Many methods of extractive metallurgy may be applied to get a pure metal from its naturally occurring ore. First ores must be concentrated and separated from their earthly impurities. Concentration of ores may be achieved by froth flotation in which an ore is contained in a froth that floats at the top of a water vat.
