processed minerals rutile sand and power
Minerals, slags, and other feedstock for the production of titanium
The first industrial synthetic rutile process, namely the Becher process, was developed in the 1960s and 1970s for the treatment of sand ilmenite in Western Australia [39]. In the Becher process (Fig. 3.10), sand ilmenite is reduced with subbituminous coal and recycled char to a metallized form. The reduction is carried out in rotary kilns at ...
