Title : Innovation potential in of the purification of iron ore tailings as a secondary source


Abstract: A significant benefit can be achieved by society by utilizing ultrafine tailings produced by mineral processing operations. Using state-of-the-art technologies for purpose this will mitigate environmental impacts, and industrial mineral ore processing plant waste can become a viable and economical source of metals. It is also possible that the waste generated by such novel technologies can potentially be more environmentally friendly. Tailing dams are one example of hazardous and polluting solid waste. Beneficiation of iron ore tailings is important in the global steel industries, from the point of view of both pollution control and the use of secondary resources. This investigation addressed the state-of-the-art beneficiation methods of ultrafine iron ore tailings to generate pellet feed fines and to prevent acid mine drainage.  Some ideas on future initiatives and potential developments are presented.

Audience Takeaway:

  • Relative scarcity of high-grade ores in the world leading researchers to recover and recycle valuable wastes (secondary sources).
  • Challenges encountered in further development of the iron ore processing industry.
  • Management of iron ore tailings: pollution control and secondary resources.
  • Beneficiation of iron from low-grade ores with high impurities (quartz, alumina, phosphorous and sulphur).
  • Analysis of state-of-the-art iron ore slimes processing.
  • Plant capacity increase.
  • Expediting the development of the efficient and operable beneficiation of iron ore.
  • How metallurgists, plant engineers and industrial researchers find practical solutions to problems they may already encounter.



Dr. Nakhaei received a Doctor of Philosophy in Mineral Processing from Amirkabir University of Technology, Iran in 2018. His research activity concerns the modeling and control for the mineral processing industrial process. He then joined the research group at the Iran Mineral Processing Research Centre (IMPRC). He has published more than 40 research articles in accredited journals.
