So before being used in aluminium production, alumina is first used to treat the gases emitted during the earlier production of aluminium. So it's a closed loop, in a sense. The aluminium reduction process requires huge amounts of electric power, so it's important to use renewable energy sources that don't contaminate the environment.
Zirconium is chiefly obtained from zirconium dioxide (baddeleyite) and zircon. These relatively heavy minerals are found in placer deposits and wind-worked sands, and are mined in Australia, South Africa, the USA, Russia and Brazil. ... Other minerals which contain zirconium are extracted as a byproduct of the mining process in many regions of ...
Zirconium is used to make the cladding for uranium oxide fuel elements. As mined, zirconium contains 1-3% per cent of hafnium, which is chemically very similar, and although it is difficult to separate the two elements this has to be done for the metal used in the nuclear industry because hafnium absorbs neutrons very strongly.
Zircon Mining. Zircon has been mined from stream gravels for over 2000 years. This early mining of zircon was mainly to obtain nice crystals for use as gemstones. Today, most zircon is produced by mining or dredging zircon-rich sediments. These sediments can be in beach, littoral, or alluvial deposits.

Feb 03, 2008· Pure zirconium is obtained using the two-step Van Arkel process. In the first step, impure zirconium and iodine are heated to produce zirconium iodide (ZrI4). In the second step, ZrI4 is decomposed to produce pure zirconium. ZrI4(s) Zr(s) + 2 I2(g) Determine the percent yield of zirconium if 48.5 g ZrI4 is decomposed and 4.50 g pure Zr is obtained. ________%
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 ...

Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals.Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last stable element to be discovered.
