The mineralogy of Hafnium - Mindat.org

Most widespread minerals containing Hafnium; This list of minerals containing Hafnium is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Hafnium mineral

Hafnium Minerals Education Coalition

Named from the Latin name of Copenhagen, hafnium is a lustrous silvery-gray metal that commonly occurs with zirconium. Most zirconium minerals contain a few percent hafnium and the two elements are most difficult to separate. Their chemistry is nearly identical. Hafnium is an unreactive metal, unaffected by air, water, most acids or bases.

WebElements Periodic Table » Hafnium » geological information

Hafnium is never found as the free element in nature. It is found in the ore alvite [(Hf, Th, Zr)SiO 4.xH 2 O] and thortveitite. Most zirconium minerals (zircon, baddelyite) contain 1 to 3% hafnium and in practice most hafnium is produced as a byproduct of zirconium production, presumably because it is necessary to remove the hafnium from the zirconium used in the nuclear industries.
