Carbothermic Reduction of Iron Oxide Waste Generated

Dec 11, 2018· In India, ilmenite is considered as a major mineral reserve for the extraction of titanium. During the processing of ilmenite to produce titanium dioxide, huge amount of iron oxide is generated and dumped as waste. According to an approximation, 0.7 ton of iron oxide waste is generated for one ton of synthetic rutile production. This waste iron oxide has great potential to be utilized as

Ilmenite Lunarpedia

Oct 13, 2014· In addition, the iron oxides present in the Ilmenite require the least energy to reduce of any oxide found on Luna. Because of this property, together with the ease of extraction from lunar sources, ilmenite has been proposed as a prime material for production of lunar oxygen. Crystallized Ilmenite is a semiconductor with a bandgap of 2.54 volts.

Recovery of iron oxide and calcium chloride from an iron

Sep 26, 2020· The ilmenite-chloride process has used for the production of TiCl4 from the ilmenite (FeTiO3) ore, which produces cyclone dust containing mostly iron chloride and includes a range of metal chlorides. The utilization of iron values present in waste chlorides of cyclone dust is becoming a crucial issue to make this process competitive. The current work demonstrates a beneficial process that can
