| Abstract: | An old tin tailings in Bolivia was treated by a new process of pretreatment - silver floatation - flotation-gravity separation combination flowsheet. High efficiency collector BK305 was used in the process of silver floatation, in the end, silver concentrates was obtained with a silver grade of 4500 g/t and a silver recovery rate of 73.63%, tin concentrates was obtained with a tin grade of 48.37% and a tin recovery rate of 52.38% by flotation-gravity separation combination flowsheet, Realizing the comprehensive recovery of valuable metals in tailings. |
