Composition and method for improvement in froth flotation
The invention provides methods and compositions for improving a froth flotation type separation. The method uses a thickener to improve the effectiveness of an emulsifier. The improvement allows for low dosages of emulsifier to work well so the emulsifier does not cancel out the effectiveness of other additives in the slurry such as collectors, frothing agents, regulators, depressors, deactivators, and/or activators.
