Zirconium ore usually contains hafnium, and it is difficult and costly to separate hafnium from zirconium ore. Zirconium in the nuclear industry needs to remove hafnium. Industrial pure zirconium is composed of 95.5%-99.2% zirconium and hafnium, among which hafnium, the maximum content allowed in the standard is 4.5%.
Zircon serves as the primary ore of zirconium metal. Zirconium is used in a variety of metal products that require a resistance to heat and corrosion. It is used to make high-performance alloys, specialty steel, lamp filaments, explosive primers, computer equipment and many electronics components.
Zirconium is widely used in the many fields, mainly used in the form of zirconium silicate, zirconium oxide in ceramics, refractories and other fields. Only 3%-4% of zirconium ore is processed into zirconium (or sponge zirconium), and then processed into a variety of zirconium material.
Headquartered in Albany Oregon, Zirconium Research Corp. has been supplying zirconium, hafnium, and niobium to industry for over 30 years. We specialize in supplying to grain refining master alloy producers and commercial users of zirconium and hafnium. ZRC specializes in supplying zirconium sponge and zirconium solids in various alloys.
World resources of zirconium are associated with those of zircon and baddeleyite, though there are still another 30 recognized mineral types which contain zirconium to a greater or lesser extent. The dominant economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4), which is found in deposits located in Australia, South Africa and India, as reported by the US Geological Survey (USGS).
Zirconium and hafnium occur most commonly in nature as the mineral zircon and less commonly as baddeleyite. Zircon is used both for its properties as a mineral and as an ore of zirconium and hafnium. Zircon is a byproduct from the mining and processing of heavy mineral sands for rutile and ilmenite. Zirconium and hafnium occur
Other important industrial compounds of zirconium include the tetrachloride ZrCl 4 and the sulfate Zr(SO 4) 2 ∙4H 2 O. Prepared by the chlorination of zirconium carbide or oxide, zirconium tetrachloride is used to produce organic zirconium compounds and as a catalyst in such reactions as the cracking of petroleum and polymerization of ethylene.
Zirconium is widely used in the many fields, mainly used in the form of zirconium silicate, zirconium oxide in ceramics, refractories and other fields. Only 3%-4% of zirconium ore is processed into zirconium (or sponge zirconium), and then processed into a variety of zirconium material.
Ore is mined from natural deposits and concentrated by various techniques. It is separated from sand by electrostatic and electromagnetic methods.Powdered zirconium silicate is also known as zircon flour. Zirconium represents a very vital and an important position in the world of industrial, medical and the defense applications as well.

The application fields of zirconium are very extensive, mainly in the form of zirconium silicate and zirconia, which are used in ceramics, refractory materials, and other fields. Only 3% -4% of zirconium ore is processed into metal zirconium or sponge zirconium, and then further processed into various zirconium materials.
The recently developed new process based on molten salt-metal equilibrium for Zr–Hf separation shows a great potential for industrial application, which is compact for nuclear grade zirconium production starting from crude ore. In the present paper, the available separation technologies are compared.

Welcome to the. Zircon Industry Association. The Zircon Industry Association (ZIA) is an independent industry association for the entire zirconium value chain, from zircon sand produced by mining and beneficiation to a wide range of downstream products, including zircon flour, opacifiers, refractory materials, fused zirconias and zirconium chemicals, metal and alloys.

The current dominant zirconium production route involves pyrometallurgical ore cracking, multi-step hydrometallurgical liquid-liquid extraction for hafnium removal and the reduction of zirconium
Zirconium, symbol Zr on the Periodic Table, is a metal most often found in and extracted from the silicate mineral zirconium silicate and the oxide mineral baddeleyite. In its various compound forms, the grayish-white zirconium is the nineteenth most plentiful element in the earth's crust, where it is far more abundant than copper and lead.
Ore of zirconium metal, ore of zirconium dioxide, whitening agents, white pigment, gemstones, radiometric dating. It is ubiquitous inside the crust of Earth. It happens as a not unusual accent mineral in igneous rocks (as primary crystallization merchandise), in metamorphic rocks and as detrital grains in sedimentary rocks.
There is another rarer zirconium ore mineral called baddeleyite (Zr02) presently only recovered from an iron ore mine in Russia. As with many technology metals, the challenge of zirconium is in the economic processing of the mineral concentrates, not in mining the resource. Much of this processing is currently being done in China.

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.
