RECOVERY OF IRON FROM COPPER FLASH SMELTING SLAGS

copper must be also as a separate phase due to the limited mutual solubility between iron and copper under these conditions. Thus, this iron alloy requires a further treatment for decreasing copper to a lower content in the final metal phase. However, the copper content in the final slag decreases to a minimum value of 0.06%
