2014 South African platinum strike - Wikipedia
South Africa is home to 80% of the world's known platinum reserves, and produces about 70% of the world's supply. Platinum prices have been flat since 2009 or so, due to weak demand for catalytic converters, the primary use of platinum in industry. Meanwhile, other costs have risen, putting pressure on the mining industry. In 2013, roughly half of South Africa mining shafts operated at a net loss.
