Extraction Of Iron Oxide From Ilmenite

01.11.2012· Separation of ferrous iron from titanium (IV) in a simulated ilmenite hydrochloric acid leachate by simultaneous oxidation and MIBK extraction was investigated. The effects of oxygen flow rate, O/A phase ratio, temperature, and hydrochloric acid concentration were studied.

Ilmenite concentrate was soluble in 1.5 M sulfuric acid and 1.5 M hydrochloric acid solutions at 90 °C. However, improved leaching was obtained with 8 and 12 M sulfuric acid solutions. The chemical leaching results for different stirring speeds showed that a speed of 750 rpm was favourable to iron and titanium dissolutions. Metal dissolution rate can be enhanced with increasing leaching time

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

11.12.2018· 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 the primary source of titanium extraction by chlorine process . Ilmenite is the most important ore of titanium mining with the chemical formula FE-TI-O3 (iron, titanium and oxygen), named for its place of discovery at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia.
