2.1 Froth flotation process. Froth flotation is extensively used to enrich sulfide minerals (galena, chalcopyrite, sphalerite, molybdenite, and pentlandite) as well as non-sulfides such as phosphate minerals, iron ores, and fine coal [1, 2].The mineral ore is ground to fine particles of typically 10 to 100µm in diameter and mixed with water to create a slurry.

Understanding the Basics of Flotation in Gold Processing. Flotation harnesses the principle of hydrophobicity – where certain mineral surfaces repel water – to separate valuable gold from waste rock. Bubbles are introduced into a pulp of finely ground ore and water, and as the hydrophobic particles attach to the bubbles, they rise to the ...
