A hydrometallurgical process for recovering some valuable elements from the dust in smelting manganese-rioh dregs is proposed.The dust is first treated with sulfurio said,and then at appropriate pH,zino together with manganese is separated by precipitation and subsequently converted into the corresponding sulfate and carbonate.The micro elements,such as gallium,indium and thallium,present in the dust,are separated by means of solvent extractions.Experimental results indicate that ootanol-(2) and N,N-di-(1'-methylheptyl) aoetamide are effective extractants.
