Design and practice of beneficiation technology of a collophanite with high sesquioxide and silica-calcareous
The main separation technologies of collophanite are introduced,including intelligent photoelectric separation,heavy medium separation,fine gravity separation,single reverse flotation,direct flotation,double reverse flotation,positive-reverse(reverse-positive)flotation.In view of the transition from single processing process to multi-process coupling,a multi-process coupling step separation flexible production process suitable for various types of low-grade silica-calcareous collophanite is proposed,and combined with the design practice of a phosphate ore concentrator in Hubei province,the general layout and plant layout are described,and some suggestions are put forward for the future construction of phosphate ore concentrators.
