Zirconium and hafnium: Old minerals finding new
Jan 30, 2019 Hafnium is a by-product of zircon refining. Global zircon production is dominated by Australia (33%) and South Africa (27%), with China (11%) and Indonesia (8%) also making significant contributions. Between 1999 and 2014, zirconium supply grew at a compound annual growth rate (CAGR) of 6.75% from 673,000t to 1,680,000t.

Zircon Geoscience Australia
Australia has the world's largest resources of zircon (about 35% of the world's zircon). Australia also produces more zircon than any other country; in 2016 alone, 560 kt of zircon concentrate was exported from Australia. Most of this material was extracted from heavy mineral sand deposits in Victoria and Western Australia.
