Titanium, zirconium resources and production: A state of the
Following the production of zirconium oxide, the production of metal is primarily carried out via chlorination, resulting in zirconium tetrachloride (ZrCl 4). ZrCl 4 is then reduced with magnesium (Mg) to produce a high purity zirconium metal in a process known as the Kroll Process. 4.2.4. Titanium4.2.4.1.
