چکیده مقاله

Ilmenite occurs in black sand at the mouth of great rivers as in India or as massive deposits like in Quebec, Canada. It is unsuitable for processing into pigment or for metal production because of its low grade. Electric furnace and hydrometallurgical methods have been developed to cope with this problem which resulted in the production of two commercial products that became known as titanium slag and synthetic rutile, respectively. The discovery that low grade ilmenite can be leached at 80oC with HCl from which synthetic rutile containing ~95% TiO2 can be precipitated renders questionable the electric furnace for treating high grade ilmenite to produce slag containing not more than 80% TiO2.
