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

Hydrogen Reduction of Regolith NASA

The baseline hydrogen reduction process for lunar regolith has two basic steps for the extraction of oxygen: — Step 1. Hydrogen Reduction of iron oxides Minerals containing iron oxides (e.g., Ilmenite FeTiO 3) are reduced by reaction with heated pure hydrogen near 900°C to form water vapor. — Step 2. Water Electrolysis
