Rhodium


Rhodium occurs invariably associated to other platinum metals. The major deposits of rhodium are located in the north of Siberia (Russia), in Ontario (Canada), and in Transval (South Africa). The extracted ores in Canada are rich in nickel and copper sulfide while those extracted in South Africa have volcanic origin, being rich in pyroxene.

Other mineral deposits that contain rhodium, although of smaller commercial importance, result from the erosion of primary deposits and is found in Russia, Colombia and in Alaska.

The rhodium abundance in the terrestrial crust is about 0,001 grams per ton.
