Title:
METHOD OF MAKING ILMENITE ORE WITH HIGH QUALITY
Document Type and Number:
Japanese Patent JP2017145475
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of making an ilmenite ore low in TiOquality be high quality by a wet leaching treatment for effectively providing high TiOconcentration titanium raw material.SOLUTION: There is provided a method of making an ilmenite ore be high quality for providing high TiOconcentration titanium raw material by separating and removing an iron component from ilmenite (FeTiO), which includes an oxidation process for conducting an oxidation treatment of the raw material ilmenite, a reduction process for conducting a reduction treatment after the oxidation process and an extraction process for melting and removing the iron component by acid after the reduction process.SELECTED DRAWING: None
