Talk:Froth flotation - Wikipedia

When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface, whereas gangue settles to the bottom. The froth is skimmed off, and processed. Sulman had previously worked on several methods for the extraction of gold, including treatment with cyanogen bromide.

Surface properties of crandallite in relation to froth flotation

The surface properties of crandallite relevant to the anionic flotation of salt-type minerals were investigated through electrokinetic, turbidity, and wettability techniques. All the tests were performed on fine crandallite particles as a function of pH and reagent concentration. The selected reagents included starch and oleic acid. From the zeta potential measurements, the iso-electric point ...

Principle: The principle of froth floatation is that sulphide ores are preferentially wetted by pine oil, whereas the gangue particles are wetted by water. Collectors are added to enhance the non-wettability of the mineral particles. Examples of collectors are pine oil, fatty acids and xanthates. Froth stabilisers are added to stabilise the froth.

Froth flotation is the process of selectively collect the hydrophobic material (water-hating) from the hydrophillic (water-loving) one. The process works by bubbling air through a slurry. The hydrophobic particles that don't want to stay in water will attach themselves to the air bubbles and get carried out of the slurry.
