Abstract
This type of deposits is the main exploration target for Pt, Ir, Os, Ru. Inferred resources of platinum group elements (PGM) from Ray-Iz are estimated at several tons. Methods of separation of rich concentrates of platinum metals by mechanical enrichment have been studied. Hydrometallurgical technology of PGM concentrates extraction from chromite ores is recommended. The expediency of PGM precipitation during processing of chromite materials at chemical plants even at low PGM content is shown. The prospectivity of chromite ores of the Polar Urals as a source of PGMs is substantiated.
