Enrichment: Gravity is the main method for enriching platinum minerals. The relative density of platinum ore is relatively large, and it can be effectively enriched by using chute, jig, shaker and wind beneficiation. Natural platinum, like natural gold, has a small surface wettability, and flotation with xanthate as a collector.
