Abstract:Agitation is an important operation unit in wet process, which is directly related to leaching efficiency and comprehensive energy consumption. The leaching and purification processes in the reactor include strong nonlinear processes of solid-liquid-gas multiphase heat and mass transfer and complex chemical reactions, and the quantitative information of internal flow field characteristics is difficult to be directly measured, and the research and development of intensive stirring technology lacks systematic theoretical guidance. The latest progress of intensive agitation was reviewed from three aspects: agitation method, measure index of agitation effect and application of agitation in modern engineering. The extensive application and prospect of digital and intelligent technology in the process of intensive stirring theory and technology research and development were also summarized.
