Sulfonated Oleic Acid (Modified Fatty Acid Collector)
Sulfonated Oleic Acid is a chemically modified fatty acid collector that combines the collecting properties of oleic acid with the water-solubility advantages of a sulfonate group. The sulfonation imparts higher water solubility and cold-water dispersibility compared to unmodified oleic acid, making it more effective in flotation circuits operating at ambient or low temperatures. It is used in carbonate, phosphate, and iron ore flotation as a high-performance alternative to conventional fatty acid collectors.
