DRY PROCESSING METHOD AND SYSTEM FOR CONVERTER SLAG IN COPPER SMELTING |
摘要 |
The present invention provides a processing method for converting slag ejected from a converter in a copper smelting process to raw materials for iron manufacture. The processing method is for converter slag containing 1 mass % or more of Cu produced in a copper smelting process. The processing method comprises a step of charging the converter slag in a reduction furnace, and a step of conducting a heat reduction of a zinc content and a copper content contained in the slag and removing a reduced zinc by volatilization in the reduction furnace. The removal of the reduced zinc by volatilization is conducted in a condition in which an air fuel ratio of a volume of air blowing to an input of a reductant is controlled to 0.25 to 1.0.
