Methyl isobutyl carbinol is an organic chemical compound commonly used as a “frother” in mineral flotation and in the production of lubricant oil additives. Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water and air bubbles.
