sodium oleate - Opis:
- The emulsified sodium vegetable oleate (ESVO) was prepared with low-cost vegetable oleate. Using ESVO as a collector, the flotation performance of fluorite had been investigated comparing with sodium oleate at a temperature of 20 ± 2 °C. 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 the zeta potential, FTIR spectra and laser grain-size tests. Both ESVO and sodium oleate changed fluorite zeta potential by electrostatic attraction and chemical adsorption, and generated calcium carboxylate on the fluorite surface. Moreover, it was concluded that higher fluorite recovery was a consequence of ESVO smaller surface tension comparing to sodium oleate.
