| Abstract: | Experimental study of valuable elements recovery was done on a gravity separation tin separation tailings which has high content of sulfur, silver and tin in Bolivia, recovery technology of tin, sulfur and silver which took the flotation main, roasting cyanide as subsidiary was confirmed. Sulfur concentrate with sulfur grade 46.70%, recovery rate 97.88%, silver grade 339 g/t,recovery rate 73.73％ and tin concentrate with tin grade 45.37%, recovery rate 52.73％ were obtained through closed-circuit test, leaching rate of roasting cyanide operation of silver was 75.10%. |
