Aiming at recovering iron from high-iron-content copper slag,this article introduced a combination technology of deep reduction and magnetic benefciation,investigated the iron recovery efciency and optimized the technical conditions.When coke powder with 86wt%fxed carbon was used as a reductant,iron was successfully extracted from the copper slag.Under the optimized condition of the coke powder content of 14wt%,the calcium-to-silicon mass ratio(Ca/Si)of 0.2,the roasting temperature of 1300 C,the roasting time of 3 h,the grinding time of 20 min,and the magnetic feld intensity of 61 kA·m 1,the iron recovery rate of the copper slag can reach 91.82%,and the extracted iron powder has an iron grade of 96.21%.With the characteristics of high iron grade and low impurity content,the extracted iron powder can be used as high-quality raw materials of weathering steel.
