Course objectives
Hydrometallurgy is a branch of extractive metallurgy that represents an important division of process engineering in countries that are richly endowed with minerals e.g. South Africa, Australia, Canada and Brazil to name but a few. Hydrometallurgical treatment of minerals, involves unit operations such as leaching, solvent extraction, electro winning and many other metallurgical processes. The most important unit in a hydrometallurgical plant is the leaching unit as the design of all downstream process is highly dependent on the products from this stage. Therefore in order to understand the principle of hydrometallurgical extraction processes, it is essential for chemical, metallurgical and mineral processing engineers to understand the principles of various systems taking place in the leaching plant. The objective of this course is to enhance the understanding of the principles and applications of the leaching of minerals during hydrometallurgical processes and to expose delegates to the relevant developments in this field.
Who should attend?
This course is designed for delegates with tertiary scientific or engineering qualifications such as Managers, Process Engineers and Technicians with the relevant experience in the minerals extraction industry. The course is suitable for people who wish to gain an in-depth understanding of leaching processes utilized in plants and also delegates who would benefit from a refresher course in the science and engineering of hydrometallurgical leaching processes. It will also benefit engineers and scientists in other disciplines such as chemistry, environmental science, or geology who are involved in the mineral and metal extraction industry
Lecturers
Prof Kwadwo Osseo-Asare is Distinguished Professor of Metallurgy and Energy and Geo-environmental Engineering in the Department of Materials Science and Engineering at Penn State University. He received his B.S., M.S. and Ph.D. in Materials Science and Engineering from the University of California (Berkeley) in 1970, 1972 and 1975, respectively. He joined the faculty at Penn State in 1976 and has published over 200 papers and supervised nearly forty M.S. and Ph.D. theses. He was elected a member of the National Academy of Engineering in 2004 for contributions to the fundamental understanding of interfacial phenomena in leaching and solvent extraction. He is the co-editor of the Hydrometallurgy Journal and has also authored a hydrometallurgical book entitled “Aqueous Processing of Materials: An Introduction to Unit Processes with Applications to Hydrometallurgy, Materials Processing, and Environmental Systems”
