摘    要：概述了流态化浸出及三相流态化技术的应用现状,简述了三相流态化的流动特征及其在浸出过程应用的几个实例,即锑精炼渣的砷锑分离过程的强化,石煤提钒浸出过程的强化以及常压氰化提金过程的强化等,其结果均优于在相同条件下的机械搅拌浸出.

Abstract: In this paper,fluidization eaching and the application of three phaser fluidization are reviewed. The characteristics of three phase fluidization are describedbriefly,and several examples of its application in leaching process, such as the separation of antimony and arsenicin antimony refining slag, leaching process in the extraction of vanadium from bone coalcyanidation of gold at normal atmosphere, etc,are given. From the results it is shown that under the same conditions fluidization leaching processes have an advantage over those by mechanical stirring
