Process For Granulation Of Slag

Such an idea is Lixivia's Selex process which is a patented water based hydrometallurgical process using a recoverable lixiviant (a liquid used to selectively extract a metal from a solid ore) that can selectively separate the complex mixture of minerals and metals that are found in steel slag which can then be sold onwardsApproximately 2 0–3 0 t of copper slag (CS) containing 35 –45 iron is generated for every ton of copper produced during the pyrometallurgical process from copper concentrate Therefore the recovery of iron from CS utilizes a valuable metal and alleviates the environmental stress caused by stockpile In this paper a new method has been developed to realize the enrichment of iron in CS
