The platinum-group metals' grades in flotation concentrates are reliably predicted by the content of related metals in ores. These dependencies are linear with high correlation coefficients: for platinum R = 0.94, and for palladium – R = 0.89. The metals flotation recovery from low-sulfidation ores may be predicted with lesser accuracy.
Platinum Palladium Flotation. Jun 24, 2017 Platinum – Palladium Flotation Summary An exploration program initiated by Johns-Manville Corp. resulted in the discovery of significant occurrences of platinum-group elements in the Stillwater complex of south-central Montana.

The traditional methods for treatment of flotation concentrates of Cu-Ni sulfide ore containing platinum-group metals are all pyrometallurgy processes. The whole craft-flow is very long and have serious environmental pollution.
Platinum Group Flotation. Virtually all platinum-group metals are recovered from copper or nickel sulfide minerals, which are concentrated by flotation separation. Smelting of the concentrate produces a matte that is leached of copper and nickel sulfides in an autoclave. The solid leach residue contains 15 to 20 percent platinum-group
