<p>A method for recovering an organic material according to one embodiment of the present invention includes the steps of: blowing molten steel in a converter; outputting the molten steel using a ladle; discharging slag from the converter using the ladle; and reducing an oxide in the slag to recover organic material through the molten steel, thereby reducing costs required to prepare high-manganese steel. In other words, an MnO oxide existing in the slag is reduced so that the Mn metal is recovered through the molten metal. Accordingly, an amount of Mn introduced in the molten steel can be reduced. In addition, the molten steel and the slag are discharged using the ladle, and a reduction agent is introduced into the ladle, so that the Mn reduced in the slag can be immediately recovered. Accordingly, an additional device and an addition process to recover the Mn are not required after the MnO is reduced. In addition, a portion of the slag produced in the converter is recycled, thereby reducing costs required to exclude and dispose the slag and environment contamination occurring in the exclusion of the slag.</p> |
