zirconium hafnium beneficiation

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.

Pronunciation: /zərˈkoʊniəm/ ​(zər-KOH-nee-əm)

Zirconium and Hafnium Statistics and Information

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 and hafnium USGS

Zirconium and hafnium are corrosion-resistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO4, or as zirconium oxide or other zirconium chemicals. Zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic radii, and ionic potentials.

Hafnium | Definition, Atomic Mass, Properties, Uses

Hafnium is chemically similar to zirconium. Both transition metals have similar electronic configurations, and their ionic radii (Zr 4+, 0.74 Å, and Hf 4+, 0.75 Å) and atomic radii (zirconium, 1.45 Å, and hafnium, 1.44 Å) are nearly identical because of the influence of the lanthanoid contraction.In fact, the chemical behaviour of these two elements is more similar than for any other pair
