In some sulphide ores of copper zinc and lead the concentration is brought byfroth flotation processin this method the advantage is taken of the preferential wetting of the ore by an oil the finely ground ore is taken in a tank containing water and 1 of pine oil or turpentine oil collectors e g pine oils fatty acids xanthates etc enhance nonwettability of the mineralRead More
The most widely accepted method for upgrading ultrafine coal isfroth flotation froth flotationis a physicochemicalprocessthat separates particles based on differences in surface wettabilityflotationtakes place by passing finely dispersed air bubbles through an aqueous suspension of particles fig 17 a chemical reagent called a frother is normally added to promote the formation of small bubblesRead More
Afroth flotation processtypically used to separate particulate materials such as coal has a mixed size feed 1 separated in a sieve bend 2 into a stream of relatively fine particles 3 and a stream of relatively coarse particles 14 the fine particles are fed to aflotationcell 7 in the normal manner while the coarse particles are mixed with wash water 16 and distributed onto orRead More
