With the lepidolite flotation tailings from Yichun of Jiangxi Province taken for search, effects of different combined processing techniques of magnetic separation and gravity separation on recoveries of tantalum, niobium and tin were compared based on its process mineralogy. It is found that the processing technique of magnetic separation combined with gravity separation, and stepwise gravity separation can lead to a Ta-Nb-Sn concentrate with higher grades but lower recoveries; while a combined process consisting of classification, gravity separation with spiral chute and then with a shaking table can produce a Ta-Nb-Sn concentrate with grades including 5.57% Ta2O5, 7.56% Nb2O5 and 45.63% SnO2, at corresponding recoveries of 41.66%, 42.28% and 31.07%.
