酸化鉱石の製錬方法
Document Type and Number:
Japanese Patent JP7124588
Kind Code:
B2
Abstract:
To provide a method for smelting an oxide ore capable of improving a grade of a resulting metal and efficiently producing a high quality metal.SOLUTION: A method for smelting an oxide ore comprises: a mixing step of mixing the oxide ore and a carbonaceous reducing agent to obtain a mixture; and a reduction step of charging the resulting mixture into a reduction furnace and subjecting the mixture to a reduction treatment to obtain a reduced product containing a metal and slag. In the reduction step, moisture generated by the reduction treatment and contained in the atmosphere gas is discharged from the reduction furnace. In the reduction step, the moisture is preferably condensed to be discharged from the reduction furnace.SELECTED DRAWING: Figure 1
