Title:
METHOD FOR RECOVERING RHENIUM, METHOD FOR SELECTIVELY RECOVERING RHENIUM FROM SOLUTION INCLUDING RHENIUM AND OTHER METALS, AND METHOD FOR INCREASING CONTENT RATIO OF RHENIUM IN SOLUTION INCLUDING RHENIUM AND OTHER METALS
Document Type and Number:
WIPO Patent Application WO/2017/018364
Kind Code:
A1
Abstract:
[Problem] To provide a method allowing for the separation of rhenium from a solution including rhenium by a simple procedure and in a shorter amount of time, and to provide a method for selectively recovering rhenium from a solution including rhenium and other metals. [Solution] A method for recovering rhenium, said method characterized by including: an addition step for adding an electron donating agent, which is an aliphatic secondary alcohol or an aliphatic secondary thioalcohol, and a ketone compound to a solution including perrhenate ions; an ultraviolet irradiation step for precipitating a reductant of the perrhenate ions included in the solution by irradiating the solution, which has undergone the addition step, with ultraviolet rays; and a fractionation step for fractionating, from the solution, the reductant of the perrhenate ions obtained by precipitation at the ultraviolet irradiation step.
