Title METHOD FOR CONCENTRATING METAL COMPOUND 新技術説明会
Abstract It is difficult to concentrate metals such as gallium from used electronic components and ore extracted from mines, while minimizing the quantity of waste liquid generated. A first solid metal compound contained in a mixture of a first solid metal compound containing a metal selected from a group consisting of gallium, indium, germanium, tellurium and cesium at a first metal content is reduced to form a gaseous metal compound, the gaseous metal compound is oxidized to form a second solid metal compound, and the second solid metal compound is collected at a second metal content which is higher than the first metal content.
