ABSTRACT
The emulsified sodium vegetable oleate (ESVO) was prepared with low-cost vegetable oleate in this paper. Using ESVO as collector, the flotation performance of fluorite had been investigated comparing with sodium oleate at a temperature of 20℃±2℃. The results of flotation showed that ESVO had better collecting performance than the sodium oleate. The interaction mechanism of these two collectors with fluorite was studied by zeta potential, FTIR spectra and laser grain-size test. Both of ESVO and sodium oleate changed fluorite zeta potential by electrostatic attraction and chemical adsorption, and generated calcium carboxylate on fluorite surface. Moreover, ESVO had smaller surface tension than sodium oleate,which make contribute to its higher fluorite recovery.
