Materials Transport in Mineral Processing Systems

Materials transport is involved in all phases of mineral processing. Bulk transport is necessary for moving materials between unit operations and through processing devices such as grinding mills. Differential transport is a primary mechanism for most separation processes. The basic mechanisms of transport and flow in particulate materials are reviewed and their role in materials handling and storage and in the performance of processing operations such as grinding and separation are discussed. Specific examples are used to illustrate current understanding of these transport phenomena and to indicate important research needs and opportunities.
