In a recent study on metal compounds, including the platinum group elements titanium and arsenic, the immunotoxicity was suggested to be dependent on speciation of the metals.

The main minerals comprise violarite, pyrite, marcasite, chalcopyrite, quartz and plagioclase. The ore averages 4.2% Ni, 3.0% Cu, and 0.01-0.2% Co and contains a small amount of platinum group elements. Magmatic Cu-Ni ore bodies are hosted in quartz schist and partially in gneiss.
Rhodium is recovered from platinum and other ores by refining and purification processes that start by dissolving the other platinum group metals and related impurities with strong acids that do not affect the rhodium itself Any remaining platinum group elements are removed by oxidation and bathing the mixture in chlorine and ammonia.
