Traditionally most accurate analysis of sulfide concentrates of Cu, Zn, Pb, Mo and Ni is done by “wet chemistry” which is long in time and only provides result of one analyte at the time. This webinar shows that precise and accurate analysis of sulfidic-base concentrates could also  be done with XRF technique in much shorter time and providing simultaneous results of all major and minor elements in the sample.
