Platinum-Group Metals
Statistical Compendium
This publication includes data through 1990.
For recent statistics, please go the the Platinum-Group Metals Statistics and Information page.
The platinum-group metals (PGM) comprise six closely related
metals: platinum, palladium, rhodium, ruthenium, iridium, and
osmium, which commonly occur together in nature and are among the
scarcest of the metallic elements. Along with gold and silver,
they are known as precious or noble metals. They occur as native
alloys in placer deposits or, more commonly, in lode deposits
associated with nickel and copper. Nearly all of the world's
supply of these metals are extracted from lode deposits in four
countries--the Republic of South Africa, the U.S.S.R., Canada,
and the United States. The Republic of South Africa is the only
country that produces all six PGM in substantial quantities.
PGM have become critical to industry because of their
extraordinary physical and chemical properties--the most
important of which is their catalytic activity. Since the mid-
1970's and continuing today, automobile manufacturers have used
catalytic converters containing platinum, palladium, and rhodium
to reduce automobile emissions. Similarly, the chemical and
petroleum-refining industries have relied on PGM catalysts to
produce a wide variety of chemicals and petroleum products.
