Document Type and Number:
WIPO Patent Application WO/2024/024585
Kind Code:
A1
Abstract:
The present invention provides a method for recovering a valuable element, the method being capable of selectively recovering Ni and Co. With respect to the above-described recovery method, a reducing agent and a slag making agent which contains CaO and SiO2 are added to an oxide which contains manganese and at least one element that is selected from the group consisting of nickel and cobalt, and the resulting mixture is heated so as to reduce the oxide. The reducing agent contains a carbon-containing material and an iron-containing material; and the iron-containing material is at least one substance that is selected from the group consisting of iron metal and iron oxide. The addition amount of the carbon-containing material and the iron-containing material is 1.0 equivalent to 1.5 equivalent in total.
