In addition to coal, it is also possible to float naturally hydrophobic minerals such as molybdenite, elemental sulfur, and talc with nonionic collectors. Nonionic collectors can also be used as extenders for other collectors. If another, more expensive collector makes a surface partially hydrophobic, adding a nonpolar oil will.

Flotation tailings. Flotation is the concentration process commonly used in the mineral processing of copper sulfide ores. The ore is finely ground and the sulfides are separated from the gangue material. This process generates large amount of tailings, containing the gangue minerals and part of the sulfides (mainly pyrite).
