Most Zr metal is produced by the reduction of the zirconium ( IV ) chloride with magnesium metal in the Kroll process.

The Kroll process converts titanium ore into titanium tetrachloride and then reacts it with liquid magnesium to produce titanium metal and magnesium chloride.

Pyrometallurgical methods are usually used to remove the remaining non-lead components of the mixture, for example the Betterton-Kroll process and the Betts electrolytic process.

Compared to the Kroll process _ the method used at the moment to extract titanium from its ore _ FFC is revolutionary, Hamilton says.
15.
The US government established a research center in Boulder, Colorado in 1944, and in late 1948, Dupont de Nemours began the commercial production of titanium using the Kroll process.
16.
De-silvered lead is freed of bismuth according to the Betterton Kroll process by treating it with metallic calcium and magnesium, which forms a bismuth dross that can be skimmed off.
17.
The main applications of magnesium are, in order : aluminium alloys, die-casting ( alloyed with zinc ), removing sulfur in the production of iron and steel, and the production of titanium in the Kroll process.
18.
This is used in the thermite reaction for preparing small quantities of metallic iron, and in the Kroll process for preparing titanium ( Ti comes at about the same level as Al in the reactivity series ).
19.
The currently known processes for extracting titanium from its various ores are laborious and costly; it is not possible to reduce the ore by heating with carbon ( as in iron smelting ) because titanium combines with the carbon to produce titanium carbide . in a Armstrong ), the Kroll process is still used for commercial production.
