microwave assisted grinding of ilmenite ore

  • Submission » DergiPark

     · Microwaves create internal friction in the material body and hence thermal stress and internal pressure. This situation can generate fractures according to the material features. Therefore, microwaves can be used in various mineral processing processes owing to this effect. In this study, the effect of microwave energy on the comminution, and flotation of a colemanite ore, which is an ...

  • Microwave-assisted grinding - IEEE Journals & Magazine

    In a microwave chamber designed to simulate a continuous throughput operation at 3 kW, the grindability of a taconite ore was improved by 13% at a bulk temperature of 197 degrees C. Because stress cracking occurred at a lower temperature, less energy was consumed, thereby improving the cost effectiveness of microwave-assisted grinding.
