The present invention relates to a method for collecting scandium from residue generated during the collection of nickel from low-grade nickel ore, through a series of procedures, including leaching, neutralization, dissolving, solvent extraction, neutralization-precipitation, and firing. The method of the present invention allows an effective collection of scandium from residue discarded at the time of nickel collection, and thus can reutilize the residue generated at the time of nickel collection and obtain scandium at lower costs. |
