Abstract
Disclosed is a method for separating nickel powders and cobalt powders from each other in a mixture of nickel powders and cobalt powders. The method includes a first step of heating a mixture of nickel powders and cobalt powders received in a container to a temperature of 350° C. to 500° C.; and a second step of reacting the heated mixture with a magnet to separate the nickel powders and the cobalt powders from each other, wherein in the second step, not the nickel powders but the cobalt powders react with the magnet, and thus the cobalt powders move out of the container and thus are separated from the nickel powders.

A method for separating nickel powders and cobalt powders from each other in a mixture of nickel powders and cobalt powders, the method comprising:
- a first step of heating a mixture of nickel powder comprising nickel and cobalt powder comprising cobalt in a container to a temperature of 350° C. to 500° C. such that the nickel powders loses its magnetic property via the heating;
- and
- a second step of reacting the heated mixture with a magnet to separate the nickel powder and the cobalt powder from each other,
- wherein in the second step the nickel powder does not react with the magnet and the cobalt powder reacts with the magnet thereby separating the cobalt powder from the nickel powder.
