  Thermally assisted magnetic separation and ... - ScienceDirect

  2019315 · Alternative beneficiation strategies are now being adopted to upgrade the iron values in low-grade iron ores that do not respond to physical beneficiation owing to their complex texture and poor liberation pattern. Thermal treatment prior to beneficiation, in order to enhance the liberation and downstream beneficiation operation, is one such method. In …
