Solvent Extraction in Hydrometallurgy: Principles, Flowsheet Design, and Selected Applications

Kathryn C. Sole, Consulting Hydrometalllurgist
Extraction 2018 is over and registration is no longer available for these courses.
Solvent extraction is a pivotal unit operation in many hydrometallurgical circuits, essential to facilitating flowsheet optimization and ensuring final product purity. Although it has been widely used in the copper and uranium industries for many decades, its use in other applications—especially those of high-tech metals, such as cobalt, nickel, scandium, and lithium—is less well known. This course provides an introduction to the use of solvent extraction in hydrometallurgical applications, and is particularly targeted at entry-level metallurgists or those who want to improve their knowledge of this technology. The basic chemical principles are outlined, including the various types of extractants and diluents employed for different applications. Consideration is given to how to conduct essential laboratory- and pilot-scale test work to generate the requisite data for flowsheet and equipment design. Operating issues and some common plant problems are then discussed. The course concludes with case studies of selected applications.
With course notes and an extensive reference list provided, as well as a focus on practical flowsheet development and troubleshooting operating issues, delegates should be well-placed to define and implement knowledge and improvements at their workplace.
The goal of this course is to expose attendees to both principles and operating practices of a range of global SX applications that will allow appreciation of synergies, advantages, and limitations of this technology and its role in flowsheet development.
