| Abstract_FL | This is an article in the field of metallurgical engineering.Torecover copper and iron from a copper smelting slag flotation tailingwith iron grade of 37.42％and copper grade of 1.86％,according to the characteristics of its ore properties,the bituminous coal was used as a reductant,the process of direct reduction roasting-magnetic separation was applied.The experimental results show that copper smelting slag,bitumite and quicklime(as a co-reducing agent)are mixed in the mass ratio of 100∶25∶20,and at the conditions of roasting temperature of 1 200 ℃,time of 80 min,the roasted ores gringding fineness of-0.045 mm 80％,and magnetic strength of 0.139 T,the copper-bearing iron ore concentrate can be obtained with an iron grade of 90.98％,iron recovery of 90.13％,copper grade of 5.82％and copper recovery of 87.38％,thus realizing the comprehensive recovery of copper and iron from copper smelting slags. |
