Tall Oil Fatty Acid (TOFA)
CAS Number: 61790-12-3
Tall Oil Fatty Acid (TOFA) is a natural mixed fatty acid collector derived from pine wood pulping processes, widely used in the flotation of iron ore, phosphate, scheelite, and other oxide minerals. Its mixture of oleic and linoleic acids provides broad-spectrum collecting ability for carbonate and oxide mineral surfaces. TOFA is a cost-effective alternative to pure oleic acid and is favored in large-tonnage iron ore and phosphate beneficiation plants.
