Extraction efficiency of metals from low-nickel matte via NH4Cl roasting-water leaching process and synthesis of (Ni,Cu,Co)Fe2O4 photocatalyst
Aiming at high energy consumption and large Co loss in the pyrometallurgy of low-nickel matte, a process of NH 4 Cl roasting-water leaching was proposed to co-extract metals, followed by the separation and utilization of metals. The effect of several factors on metal extractions in NH 4 Cl roasting...
