Currently, there are two major economic exploitation of titanium ore - rock and placer. As shown, the majority of titanium dioxide pigment in the process before it is used, the need for enrichment or concentration and other processing methods to increase the content of Ti0 2 in the feedstock. As shown in FIG processing technology, using conventional processing methods such as re-election, magnetic separation, electrostatic and other selected beneficiation, smelting furnace is further processed into high iron slag, and reducing the production of synthetic rutile chemical treatment.
