Becher process - Wikipedia

The Becher Process is an industrial process used to produce rutile, a form of titanium dioxide, from the ore ilmenite.It is competitive with the Chloride Process and the Sulfate Process, which achieve similar net converstions.. With the idealized formula FeTiO3, ilmenite, contains 55-65% titanium dioxide, the rest being iron oxide.The Becher process, like other beneficiation …

pigment production through the chloride process. keywords: titanium slag, synthetic rutile, chloride process, sulfate process, acid leaching, TiO 2 pigment 1. Introduction Titanium is relatively abundant in the earth's crust, which is usually found in igneous and metamorphic rocks as ilmenite (FeTiO 3), rutile (TiO 2) and titanomagnetite (Fe 2

Ilmenite for pigment and metal production

For these reasons, titanium slag was used only for making pigment by the sulfuric acid process [7]. The slag was treated in the same way as ilmenite with the exception that no separation of ferrous sulfate was necessary because the bulk of iron was already separated by reduction in the earlier step (Figure 13).
