2. Flotation Fluids . Since parasite eggs will sink in water, salt or sugar solutions are used to concentrate and separate eggs from most fecal debris. The most commonly used flotation fluids are magnesium sulfate (Epsom salts), sugar, sodium nitrate, and zinc sulfate. A specific gravity from 1.2 to 1.3 is best for floating most eggs.

Copper Sulfide Flotation - Mineral Processing & Metallurgy
Standard "Sub-A" Flotation Machines are used for both the rougher and cleaner circuits, where their cell-to-cell principle gives both high recovery and a good grade of concentrate. The rougher concentration is accomplished in 6 or 8-cell flotation machines, with the concentrate from each going to a separate bank for cleaning and re-cleaning.

Removal of Sulfate Ions by Precipitation and Flotation
ABSTRACT. The removal of sulfate ions from natural waters, as well as from industrial effluents of different origins, is a problem, considering that most of the proposed processes are inefficient and have a high cost, mainly when reducing the sulfate ion concentration to values below 500 mg.L-1 is required. The flotation technique, combined with precipitation, has proven to be efficient for ...
