Concentration and Purification of Leach Solutions is the third in a series of four hydrometallurgy courses by the author, written for university students as well as practicing engineers and metallurgists. The Hydrometallurgy series covers the elementary theoretical basis of solution chemistry, the engineering aspects, and the technical applications for a large variety of raw materials, e.g. metals, oxides, sulfides, phosphates, silicates, and others. It also covers the purification-concentration steps such as adsorption on activated charcoal, ion exchange, and solvent extraction. Finally, the general aspects of precipitation from aqueous solutions are covered with numerous examples. The series is characterized by clear and simplified flowsheets, numerous chemical equations written mainly in ionic form, many illustrations for equipment and plants, and finally a lucid style presenting the facts point by point as concisely as possible. Hydrometallurgy 3 - Concentration and Purification of Leach Solutions covers the processes of activated charcoal adsorption, ion exchange and solvent extraction and how they relate to the concentration and purification of leach solutions.

Hydrometallurgy 1 - Introduction to Leaching covers solution chemistry, leaching mechanisms and processes, leaching methods and equipment, engineering aspects and microorganisms. Solution chemistry introduces the structure of minerals and water, elementary concepts of acids and bases, oxidation and reduction, complex formation and precipitation. These concepts are included because many metallurgy students do not have this chemistry background. The rest of the course is devoted to the general aspects of leaching of ores and concentrates, the reagents used, methods and equipment, the engineering aspects, and the role of microorganisms.

About the Course In this introductory course, students explore the science behind the processes used in today's mineral processing industry. The concepts of reaction kinetics are introduced and applied to the chemistry and physics in mineral processing operations. With ever more difficult ores to process, we bring a new approach to mineral processing by focusing on understanding the consistency of science at the molecular level. This course explores the improved use of old techniques and development of new ones will advance the industry into the 21st century.​ Students will leave this course with a solid grasp of reaction kinetics concepts such as surface charge, reaction selectivity, application characteristics of soluble and insoluble reagents, equilibrium, chemical dispersion characteristics, and practices that will help them troubleshoot and improve mineral processing operations and increase plant efficiency. About the Audience This course is for individuals interested in the science behind mineral processing operations. Examples of those who may be interested include: mineral processors, metallurgists, mineral processing researchers, engineers, and plant managers.
