Abstract

A sulfate process for producing titania from a titaniferous material (such as an iron-containing titaniferous material; such as ilmenite) is disclosed. The process includes precipitating titanyl sulfate from a process solution produced in the process. The titanyl sulfate precipitation step includes subjecting the precipitated titanyl sulfate to a shearing action during the course of precipitating titanyl sulfate from the process solution or after precipitation has been completed.
