The course focus in on metals recovery from mineral recourses by hydrometallurgical technology. Ore formation, geology and mineralogy is reviewed. Mining techniques are also briefly reviewed and generic hydrometallurgy flowsheets are discussed. Mineral upgrading methods are discussed followed by leaching fundamentals (chemistry-thermodynamics-kinetrics), including bioleaching technology, and equipment. Solid-liquid separation and solution purification techniques such as by chemical precipitation, ion exchange and solvent extraction are also discussed. Examples from pure metal recovery and effluent treatment; residue disposal technologies for environmental compliance are presented. Finally, process development, plant design, plant control strategies, Economic, Social and Environmental Considerations, followed by several industrial examples is offered.
