Abstract
To concentrate metals such as gallium from ore which is extracted from mines or used electronic components while suppressing the quantity of waste liquid generated is difficult. A first solid metal compound which contains a metal selected from a group consisting of gallium, indium, germanium, tellurium, and cesium at a first metal content in a mixture of the first solid metal compound 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.
