TESTING FLOTATION FROTHERS

Flotation – A flotation frother – like Methyl Isobutyl Carbinol, 2-Ethyl Hexanol, or terpenic oil – and a "slurry" of fine powder and water are then introduced to a water bath (i.e., flotation cell) which is aerated, creating bubbles. Frothing – A stable froth is formed on the surface of the flotation cell from the aeration. The ...
