DetailsThe froth flotation process typically involves a series of multiple flotation cells arranged in a sequential manner. This configuration allows for a step-wise separation of valuable minerals from the ore, with each cell playing a specific role in the overall process [].The use of multiple cells in series enhances the efficiency of the flotation process by …
DetailsUnderstanding 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 ...
