Title:
METHOD FOR CONCENTRATING METAL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2014/034925
Kind Code:
A2
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.
