Abstract
Disclosed herein is a method of reducing slag, including the steps of: examining the components of slag to be reduced, and setting a target composition ratio after reduction; determining the mixing ratio and input amount of a complex reducing agent of a plurality of reducing agents in accordance with the set target composition ratio to determine the complex reducing agent; and supplying the complex reducing agent into molten slag to reduce the slag. The method is advantageous in that the reduction efficiency of slag can be maximized, various kinds of reducing agents can be efficiently used, and the recovery amount of valuable metals can be increased, thus reducing cost.
