    Abstract: The present invention relates to a method for recovering nickel and cobalt from a nickel, iron, and cobalt-containing raw material. According to the present invention, high concentrations of valuable metals, such as nickel and cobalt, can be recovered from a raw material containing nickel, iron, and cobalt, and especially, the concentrations of nickel and cobalt are low and the concentration of iron is high, and thus when nickel is leached, and relatively large amount of iron is leached, whereas a small amount of nickel is leached. Therefore, the present invention can be more suitably applied in the smelting of nickel ore in which the separation of iron and nickel is difficult.
