The production of high-titania products from ilmenite by a sulphuric acid process

Ilmenite obtained from Westland beachsands is a potential titanium raw material. High-titania products suitable as a feed material for the production of titanium dioxide pigments can be produced from the ilmenite by digestion in mediumstrength sulphuric acid. This process, evaluated in this paper, offers the pigment producer a reliable feedstock and reduces his pollution problems.
