192 ZIRCONIUM AND HAFNIUM - prd-wret.s3-us-west-2 192 ZIRCONIUM AND HAFNIUM (Data in metric tons unless otherwise noted) Domestic Production and Use: In 2018, two firms recovered zircon (zirconium silicate) from surface-mining operations in Florida and Georgia as a coproduct from the mining of heavy-mineral sands and the processing of
Hafnium - Wikipedia However, because of hafnium's neutron-absorbing properties, hafnium impurities in zirconium would cause it to be far less useful for nuclear-reactor applications. Thus, a nearly complete separation of zirconium and hafnium is necessary for their use in nuclear power. The production of hafnium-free zirconium is the main source for hafnium.
Zirconium and Hafnium Statistics and Information - usgs.gov The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
Zirconium - Wikipedia Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.
Zircon Sponge & Alloys Zircon Industry Association Zirconium metal, or sponge, is used mainly in the nuclear industry with a requirement for minimum content of hafnium. The chemical and physical similarity of zirconium and hafnium means that separation of these two metals is difficult.
