====Hunter process====
The Hunter process was the first industrial process to produce pure metallic titanium. It was invented in 1910 by [[Matthew A. Hunter]], a [[chemist]] born in New Zealand who worked in the United States.<ref>{{cite journal | last1 = Hunter | first1 = M. A. | year = 1910| title = Metallic Titanium | url = | journal = J. Am.

Dilute [[hydrochloric acid]] is then used to leach the salt from the product.<ref>{{Cite encyclopedia |entry=Hunter process |dictionary=A Dictionary of Chemical Engineering |date=2014 |url=http://www.oxfordreference.com/view/10.1093/acref/9780199651450.001.0001/acref-9780199651450-e-1447 |url-access=subscription |language=en|doi=10.1093/acref/9780199651450.001.0001|last1=Schaschke |first1=Carl |publisher=Oxford University Press |isbn=978-0-19-965145-0 }}</ref>
