Abstract (en)
A process for recovering titanium dioxide from a feed comprising titanium dioxide fines is disclosed. The process comprises the steps of (A) separating particulate matter having a Tyler Standard screen size of about 6 or larger from said feed; (B) removing liquid from said feed; (C) dividing said feed into (i) a concentrate having a relatively high concentration of titanium dioxide, (ii) middlings having a lower concentration of titanium dioxide than said concentrate, and (iii) tailings having a lower concentration of titanium dioxide than said middlings; and (D) removing liquid from said concentrate to form a product comprising titanium dioxide.
