Zirconium - Wikipedia

The name zirconium is taken from the name of the mineral zircon, the most important source of zirconium. The word zircon comes from the Persian word zargun زرگون, meaning "gold-colored".[5] It is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium.

Commercial sources of hafnium-bearing zirconium minerals are found in beach sands and river gravel in the United States (principally Florida), Australia, Brazil, western Africa, and India. Hafnium vapour has been identified in the Sun’s atmosphere.

1 Thomas E. Garner, Zirconium and Hafnium …

zirconium and hafnium solution is passed through a series of liquid-liquid extractions, stripping, and scrubbing steps to separate zirconium from hafnium. Liquid-liquid extraction, using methyl isobutyl ketone (containing thi ocyanate) as a solvent, separates zirconium from hafnium by preferentially extracting hafnium into the solvent phase.

Hafnium (Hf) – Alkane's Destiny to Dominate

The production of hafnium-free zirconium is the main source for hafnium. The chemical properties of hafnium and zirconium are nearly identical, which makes the two difficult to separate. After zirconium was chosen as material for nuclear reactor programs in the 1940s, a separation method was developed.
