Water in Fluorspar Flotation. Water has received little attention as a variable in flotation, even though it is a known fact that water hardness often has an adverse effect on purity and recovery, particularly on the flotation of non-metallic minerals. Because of this fact, process water used in some flotation plants is treated to reduce ...

Nov 22, 2015 Flotation is the process that concentrates the ore. This is done by agitating the ore slurry in cells with air bubbles. By adding a combination of fatty acid reagents, the fluorspar in the ore attaches itself to the air bubble to float to the top of the cell. This product is skimmed off leaving the waste in the bottom of the cell.
A method is disclosed for beneficiating a fluorspar concentrate containing apatite as a gangue mineral, which includes further concentrating the fluorspar by a froth flotation process wherein the apatite is collected and floated with a cationic reagent in an acid flotation circuit and the fluorspar is depressed with fluoride ions.
