Abstract:
The demand for PGEs mineral resources in China shows an increasing trend, and the external dependence is as high as 98%, which is a huge supply risk.This paper summarizes geological environment, distribution, and genetic type of the world-class PGEs deposits, and we also count supply and demand date of PGEs in China and the world in recent ten years(2011-2019), such as the exploration, consumption and the industrial chain.And then, we forecast the PGEs consumption, supply patterns and trends of China in next few years, and we also offer reasonable suggestions.Research shows that: ① Global PGEs reserve is scarce, but the distribution is more concentrated, mainly distributed in South Africa, Zimbabwe, Russia and North America.China's proved PGEs resources accounted for < 1% of the world's resource, therefore external dependence is very high; ② the genetic types of the PGEs deposit is various, but the magmatic PGEs deposits, especially outputed in mafic-ultramafic volcanic rocks, is the most important, with 10% large-superlarge deposits accounting for 85% of the world's PGEs resources; ③ The world's and China's PGEs exploration is at low ebb, and the increasing of PGEs resources and supply is not obvious.Especially, most of the world-renowned mining companies are mainly controlled by European and American, South African and Russian mining oligarchs, and China's large PGEs mining are relatively weak in international competitiveness; ④ China has established a relatively complete PGEs industrial chain, and the demand for PGEs in China in the next ten years may be as high as 160~185 t, with an average annual growth rate of 2.67%.Therefore, it is imperative to establish strategic reserve, stabilize global supply and strengthen recycling.
