Preparing of Glass-Ceramics and Recovering of Iron from Copper Slag

Abstract:

Copper slag, containing more than 40 wt% iron, is often used for pavement of roads, building bricks and cement etc. The level of this traditional utilization technology is very poor. In this study, a new method of comprehensive utilization of copper slag was investigated. The iron of copper slag was recovered and the residual slag was transformed into glass-ceramics within the same process involving iron reduction, iron-glass separation and glass crystallization. The experimental results indicated that the ratio of iron recovery was more than 99% and the crystalline phase of the obtained glass-ceramics was diopside. With the extension of crystallization time, the content of crystalline phase and the size of crystals of the glass-ceramics increase.
