| Abstract Scope |
Co-containing metallurgical slag has been regarded as one kind of potentially recyclable Co resources. Pyrite cinder is a typical metallurgical slag produced in sulfuric acid industry, which contains a significant grade of valuable metals, such as iron, cobalt, etc. However, it is very difficult to utilize the pyrite cinder due to its low surface activity. In this study, an acid leaching process was used to separate iron and cobalt from the pyrite cinder. The results indicated that the leaching efficiency of cobalt achieved more than 98% under optimal conditions. Under the phosphate system, most of iron formed insoluble iron phosphate precipitate, which was easily separated from cobalt by filtration. The cobalt was recovered by organic extraction and the battery-grade precursor of iron phosphate was finally obtained through purification. |
