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%.
