摘要：

The performance of a novel collector 2- methyl -5- hexyl xanthate was evaluated for the flotation tests using pyrite and ores containing different gold grades from two different deposits in comparison with butyl xanthate. Using FTIR, UV-vis spectroscopy and flotation theory, the mechanism of new collector ZJ-6 and structure-activity relationship were studied. The results show that the maximum absorption wavelength of the new collector ZJ-6 peaks at larger value is higher than that of other collectors. The affability of collectors to sulfide significantly increases with the increase of alkyl chain length till butyl, and from then on only slight difference is observed. In other words, by modulating the alkyl chain length and the electronic effect of nonpolar groups, the affability of collectors to sulfide compounds and hydrophobicity can be enhanced, and hence the performance of collectors is improved. ©, 2015, Central South University of Technology.
