CLASSIFICATION OF FLOTATION FROTHERS Mark II

By Ph.D. Natalia Petrovskaya, 2018

Heteropolar

Ionogenic

• Anionic: Alkyl aryl sulfonates (Detergent) and Phenols (Cresol, Xylenol). (Alkyl aryl sulfate and Carboxylic acids have a foaming effect. Alkyl aryl sulfate and Carboxylic acids are hydrophobizators)

• Cationic: Pyridines (Amines have a foaming effect. Amines are hydrophobizators)

Non-ionogenic

• Alcohols: Methyl isobutyl carbinol, Amyl alcohol, Pine oil, Terpene alcohols, Cyclohexanol, Aliphatic alcohols

• Esters and Ethers (glycol): Polyethylene glycols, Polypropylene glycol, Dialkyl phthalates, Вimethyl phthalate.  (Daufros)

Colloidal: Saponin, Peptone, Gelatine, Albumin, Peptin, Casein

With uncertain chemical composition: Mixtures, chemical industry waste or other frothers

Others: (Soda and Lime have weak foaming effect (and other salts). Soda and Lime are modifiers)
