The six platinum group metals (PGMs) occur together
in nature alongside nickel and copper.
South Africa is the world's leading platinum producer
and the second largest palladium producer after Russia where production
is concentrated in the Norilsk region.
All of South Africa's production is sourced from
the Bushveld Igneous Complex, which hosts the world's largest resource
of PGMs. In addition to platinum and palladium, these mines also
produce rhodium, ruthenium, iridium, gold, silver, nickel, copper,
cobalt, ammonium sulphate and sulphuric acid as by-products.
Platinum and palladium have the greatest economic importance and are found
in the largest quantities. The other four - iridium, rhodium, ruthenium and
osmium - are produced only as co-products of platinum and palladium and are
never likely to be mined for their own sake.
It is a capital and labour intensive industry, taking
up to six months, and requiring 7 to 12 tonnes of ore to produce
one troy ounce (31.135 grammes) of platinum. Companies are investing
heavily in exploration and production facilities to ensure the
future supply of these vital metals. more >> |
