Abstract: In order to solve the problems of typical tailings resource utilization from Panxi region, the technology of comprehensive utilization of the low-grade tailings was studied. Based on the research results of mineralogy of tailings process, the technical route of "floating-magnetic-gravity echelon recovery of useful mineral——silicon fertilizer from tailings" suitable for the tailing property is determined. On the basis of the recovery and utilization of valuable elements, the hard-to-use tailing resources are transformed into mica concentrate withyield of 11.78%、K₂O grade 7.77%、recovery rate of 25.92% and silicon fertilizer products with effective silicon more than 40%. The tailings can be reduced by 64.66%, thus realizing the resource recovery and reduction of tailing.
