Oxidative modification of industrial basic oxygen furnace slag

The oxidation slag was taken out from the corundum crucible and ground to a certain size in the ball mill. The oxidation slag was separated by a wet magnetic separator at 50 mT, as shown in Fig. 1 b. 5 g of oxidation slag powder was added to the beaker followed by 50 mL of deionized water to prevent coagulation of the slag particles. After A novel technology, modified roasting in CO–CO2 mixed gas and magnetic separation, was presented to recover iron from copper slag. The effects of various parameters such as dosage of flux (CaO), gas flowrate of CO and CO2, roasting temperature, roasting time, particle size of modified slag and magnetic flux density on the Recovery of iron from copper slag via modified roasting in
