Estimated world thorium resources

There is no international or standard classification for thorium resources and identified Th resources do not have the same meaning in terms of classification as identified U resources. Thorium is not a primary exploration target and resources are estimated in relation to uranium and rare earths resources.

Monazite is extracted in India, Brazil, Vietnam and Malaysia, probably less than 10,000 t/yr, but without commercial rare earth recovery, thorium production is not economic at present. Chinese production is unknown. The 2014 ‘Red Book’ suggests that extraction of thorium as a by-product of rare earth elements (REE) recovery from monazite seems to be the most feasible source of thorium production at this time.
