  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.
