The paper recovered the tin from a refractory tin ore in Kazakhstan. The grade of tin in raw ore is 1.19%. Through technological mineralogy study, we found the tin was mainly in the forms of cassiterite and stannite. Considering the gravity process would make the stannite lost in tailings because of its small specific gravity, we explored the flotation to recover the tin. In fact, the grade and recovery of tin were bad by collectors contrast test. Finally, we adopted gravity flowsheet to recover cassiterite. The recovery of tin is not high because the tin in the form of stannite lost in tailings. As a result, the tin concentrate with a grade of 21.56% and the recovery of 52.90% were obtained.
