  Recovery and preparation of high-grade silica from iron ore …

  2023615 · Coincidently, high‑silicon IOTs contain numerous quartz resources. However, because of the backward separation and purification technology, most researchers mainly focus on the recovery of Fe rather than silica from IOTs [ 23, 24 ]. Therefore, it is vital to develop a method for silica separation and purification from high‑silicon IOTs.

  Separation of cobalt from slag of nickel pig iron using …

  However, slag of nickel pig iron still contains multicomponent minerals (Fe, Mn, Co, Pb, Cu), which is high value, one of them is cobalt. To separate cobalt from other components and obtain cobalt with high purity, it can be done by the solvent extraction method from the sulfuric acid leaching solution. In this study, the Taguchi experiment ...
