Abstract
To investigate the platinum-metal mineralization in Guli chromitite, the gravity concentrates recovered from the heavy fraction of a 2-km chromitite sample with a PGE content of 0.2 ppm was studied. The sample was broken up by the electric pulse method, which guarantees maximum preservation of accessory mineral grains in the resulting product. The polished sections of the concentrate were analyzed on a CamScan scanning electron microscope. Microprobe analysis of the gravity concentrate of the first PGM-enriched fraction revealed several cubic grains, made up predominantly of tetraferroplatinum. Also identified as inclusions were iridosmine and an unnamed PGM with the formula RhNiAs.
