Chloride grade ilmenite is …
Ilmenite is the primary ore of titanium metal. Small amounts of titanium combined with certain metals will produce durable, high-strength, lightweight alloys. These alloys are …
Ilmenite derived from hard-rock sources is usually beneficiated into Ti-slag, thereby adding considerably to energy requirements. ... SeAPM was collected surrounding an iron ore processing and steel industrial complex in Vitória city (Espírito Santo, Brazil) area. Water samples were collected daily for physicochemical analyses, and every 3 ...
The author reviews the feasibility of producing oxygen from the ilmenite in a pyrometallurgical process, reviewing the reactions proposed through thermodynamic calculation with the Software HSC ...
The technology used is called the Becher process and was developed by a joint industry and Australian government initiative in the early 1960s. In the Becher process, ilmenite concentrate containing 55%-65% TiO 2 (the rest is mainly iron oxide) is fed to a rotary kiln to reduce the iron oxide to metallic iron. Ilmenite grains are converted to ...
From ilmenite ores, through the Becher process, synthetic rutile is produced, which is slightly yellowish and almost transparent in colour (Pellegrino and Lodhia, …
The theoretical TiO 2 content in ilmenite is 52.7% and the specific gravity of ilmenite is high (ilmenite is considered to be a heavy mineral with the specific gravity of about 5). Fig. 2 shows that ilmenite crystallizes in the trigonal form and Fe 2+ and Ti 4+ ions occupy alternating layers perpendicular to the trigonal c axis.
