RESEARCH ON THE DESIGN AND PROCESSING CHARACTERISTICS OF 320 m~3 AIR-FORCED MECHANICAL FLOTATION CELL

摘要

In recent years, large scale flotation cells have been used very well in China. The design principles ofrnflotation cell in different processes are established, the trend extrapolation method of flotation cellrnscaling up is developed, which based on stepwise regression and similar enlargement at the samernReynolds number in different size flotation cells. The technical way and method for flotation cellrndevelopment is formed, which base on separation performance, control strategy, arrangement andrnprocess. In the 320 m~3 air-forced flotation cell which is the biggest flotation cell in the world, mineralrnparticles distribute uniformly, which indicates that the mineral grains suspend well in flotation cell.rnThe enrichment ratio of copper is up to 20.62 through a single set of 320 m~3 flotation cell, andrnthe enrichment ratio of sulphur is up to 71.44. The successful application of 320 m~3 flotation cellrnindicates that China becomes one of the several countries in the world who masters the key technicalrnof flotation cell scaling up.
