Scope The Hydrometallurgy technical theme is one of four technical themes for Extraction 2018 and consists of three symposia:

C-1: Hydrometallurgy 2018 (the symposium)
C-2: The Gordon Ritcey Symposium: Advances in Hydrometallurgical Solution Purification Separations
C-3: Processing of Critical Materials

Hydrometallurgy 2018 will provide a great opportunity to share and learn about research and industrial experiences in all aspects of hydrometallurgical extraction, purification, and recovery of base, critical, rare, and precious metals. Hydrometallurgy 2018 will include the Gordon Ritcey Symposium on purification by solvent extraction and ion exchange technologies as well as the Processing of Critical Metals Symposium that focusses on critical metals such as lithium, scandium, rare earth elements, etc. The conference will cover all aspects of hydrometallurgy, including leaching, solvent extraction, ion exchange, electrorefining, electrowinning, process control, precipitation, environmental issues, energy efficiency, recovery from secondary sources, by-product recovery, and modelling. The technical committee welcomes submissions of presentations in any area of hydrometallurgy theory or practice.
