A brief introduction to production of titanium dioxide and titanium

In some operations, titania slag from electric arc processing of ilmenite is "upgraded" to higher purity by heat treating titanium slag to make it more amenable to impurity removal through subsequent pressure leaching in hydrochloric acid [9]. Upgraded titanium dioxide or titania slag is also referred to as synthetic rutile.
