Title:
METHOD OF RECOVERING VALUABLE MATERIAL
Document Type and Number:
Japanese Patent JP2018109208
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method in which, from a hydrochloric acid acidic solution containing selenium and ruthenium and/or tellurium, selenium and ruthenium and/or tellurium are efficiently separated by precipitation, to recover valuable material.SOLUTION: A method of recovering valuable material includes the steps of: adding water-soluble ketone to a hydrochloric acid acidic solution containing selenium and ruthenium and/or tellurium; stirring it until the hydrochloric acid acidic solution, to which the water-soluble ketone has been added, becomes cloudy; supplying the hydrochloric acid acidic solution being cloudy with reducing sulfur, to precipitate valuable material containing selenium and ruthenium and/or tellurium; and recovering the precipitated valuable material.SELECTED DRAWING: None
