Froth flotation process

Apr 15, 2021

Froth Floatation Process. In some cases for example, sulphides ores of copper, zinc and lead concentration is brought by this method. In this method advantage is taken of the referential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or terpentine oil. A strong current of air is blown
