Course Objective

This course will review the fundamental of sedimentation, filtration, drying and dust collection. The separation of solids from fluids is one of the important subjects in the field of mineral processing. Especially in treating fine solids, the importance of dewatering muds or of settling dusts becomes considerable. Mechanical separation of solids from liquids is accomplished by thickening and filtration. Ultimate moisture removal is obtained by drying. These procedures are important not only in mineral processing, but also in water purification, in mining and smelting operations. This course will teach theory of these processes, methods and equipment used in these processes, examples of their applications.

Learning Outcomes of the Course Unit

1   understand and be able to express the fundamentals of dewatering (sedimentation, thickening, filtration) and drying processes
2   able to discus and evaluate the technical, environmental and economic aspects of solid-liquid separation, drying and dust collection systems
3   develop an understanding of interaction of dewatering and drying processes with other disciplines such as chemistry, thermodynamics, fluid mechanics, mineral processing
4   develop the knowledge on the chemical and physical processes
5   advance independent learning skills, follow developments related to dewatering and drying processes, and improve team work skills
6   develop analytical thinking skills, capability to perform the basic engineering calculations, and provide the ability to evaluate and write the results of the experiments
7   develop conceptual process flow sheet for solid-liquid separation and drying systems in mineral processing and other industrial fields
8   analyze, understand and assess the economic, environmental and social aspects of various industrial dewatering and drying processes
