Iron Control (Fe) in Hydrometallurgy

4th International Symposium (Fe-Hydrometallurgy)

COM 2016 - High Pressure Pump, Iron Control (Fe) Hydrometallurgy

Affiliate programs include: Two day Short Course being held Sept. 10 and 11 (details below) and an Industrial Tour of CCR Copper Refinery and Canadian Electrolytic Zinc (both Glencore Companies) on Sept. 16 (…info).

The control, stabilization and disposal of iron plays a key role in the design and operation of most hydrometallurgical processes. In some processes, the iron dissolves and is precipitated in a subsequent operation; in other processes, such as those used to leach nickel laterites and bauxite, the iron is rejected in situ. In all the processes, the environmentally acceptable and economically sound disposal of the iron is of paramount importance to both existing operations and developing technologies.

The Fourth International Symposium on Iron Control in Hydrometallurgy – building on the successes of the previous three symposia in Toronto (1986), Ottawa (1996) and Montreal (2006) – will bring together plant operators, consulting engineers and researchers to discuss the theory and practice of the iron control problem as it relates to the processing of base and precious metals, the leaching of nickel laterites and bauxite, and the treatment of pickle liquors. The key role of iron precipitation in impurity element containment will also be considered. The Symposium will provide a forum for the international metallurgical community to review the recent technological developments in iron control, stabilization and disposal. The meeting will facilitate a better understanding of the theory and practice of iron control in hydrometallurgical processes and the identification of innovative iron control technologies. The meeting addresses iron chemistry, process design, equipment selection and plant economics. This symposium is organized by the Hydrometallurgy Section of the Metallurgy and Materials Society of CIM.


Topics include:

  • Iron control technologies and plant descriptions
  • Iron control during the leaching of nickel laterites and bauxite
  • Treatment of pickle liquors and iron solutions
  • Role of iron precipitation to control impurity species such as arsenic
  • Emerging iron control technologies
  • Fundamental aspects of iron control
  • Thickening and filtration of iron precipitates
  • Stabilization and disposal of iron residues and precipitates, including red muds
  • Environmental considerations, trends and regulations related to iron residue disposal
  • Uses and applications of hydrometallurgical iron.


The proceedings of the Symposium will be published in electronic and print format and will be available at the meeting. Both the Symposium and its proceedings will be in English. All papers will be refereed and edited prior to final acceptance and publication.


Short Course on Iron Control (Two-Days, Sept. 10-11, 2016)

A one-and-a-half or two day short course will be offered immediately before the Symposium, on Saturday, September 10 and Sunday, September 11, 2016. The short course is designed to complement the industrially focused Symposium program, and will provide an in-depth study of the fundamentals and practice of iron control in hydrometallurgy. The short course will be given by a number of lecturers of international stature in their fields of expertise.
