Question

explain froth floatation process for the concentration of sulphide ore for 6 marks question

Answer 1

Sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by water. In this process a suspension of a powdered ore is made with water.
Collectors like pine oil, fatty acids and xanthates are added to it. Froth stabilizers like cresols, aniline stablize the froth. The mineral particles become wet by oils while gangue particles by water. The mixture is agitated with the help of mechanical stirring by passing blast of air. The froth is form which is lighter and skimmed off. The froth is dried for recovery ofthe ore particles. Hope you get it. Please follow me and mark as brainliest.
