The results show that the iron nuggets and alumina slag can be obtained in a short time through a semi-smelting reduction and magnetic separation process. The maximum particle size of iron nugget is about 15 mm and the recovery rate of the iron and Al2O3 grade of the alumina slag are 96.84 wt % and 43.98 wt % respectively.

Optimization of magnetic separation process for iron recovery

To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron M-Fe in the slag. The final recycling efficiency was evaluated by calculating the percentage of recycled M-Fe to the maximum amount of M-Fe
