Abstract:With the constant improvement ofS mineral automatic analysis technology and development of EPMA, LA-ICPMS,TOF-SIMS and X-ray absorption fine structure analysis technique, based on “rare” “associated” and " fine grain "of four rare "( REE, rare element, scattered elements and precious metal elements) and other key metal minerals, some in-depth study on the occurrence state of elements and the mechanism of action between flotation agents and mineral surfaces have been done. For these study, some technological difficulty have been solved, to promote the process mineralogy research to direction of more detailed, faster".
