Processes Free Full Text Extraction of Cobalt and Iron

In this study, oxidizing roasting, segregation roasting, and magnetic separation are used to extract cobalt and iron from refractory Co bearing sulfur concentrate. The Co bearing sulfur concentrate containing 0.68% Co, 33.26% Fe, and 36.58% S was obtained from V Ti magnetite in the Panxi area of China by flotation. Cobalt pyrite and linneite were the Co bearing minerals, and the
