Rate Processes in Multiparticle Metallurgical Systems

摘要: In the preceding chapter, kinetic behavior of individual particles isolated in an infinite fluid medium has been discussed. The various steps or combinations which can control rate heterogeneous reactions were identified and appropriate types mathematical models to describe particle reviewed. present consideration is extended multiparticle systems. By definition, a system consists assembly that make up disperse phase plus environment surrounding makes continuous processing vessel. Virtually all particulate assemblages encountered extractive metallurgical practice are polydisperse nature, i.e., being processed have broad distribution properties such as size, mineralogical composition, etc., contribute overall system. addition, practical systems often interact with one another and/or environment. If wishes accurately design reactor, optimize existing operation, specify effective automatic strategy for process, it necessary be able describe, quantitative terms, influence material property distributions particle-particle particle-fluid interactions on reaction
