Yunnan tin ore reserves of five hundred thousand tons of high iron and low tin, the iron content of about 50%, mainly in the form of limonite, hematite; tin containing about 0.35%, mainly in the form of cassiterite. In order to find the main recovery process of tin metal and comprehensive recovery of iron metal, the mineral processing flowsheet and possible ore dressing indexes are explored. In order to recover valuable elements such as tin and iron in the ore, two kinds of technological tests, including gravity separation of tin, magnetic separation of iron, magnetic separation of iron and gravity separation of tin, were carried out respectively. The results show that the magnetic products are obtained by 1 coarse 1 fine magnetic separation when the ore is grinded to-0.6 mm, and the non-magnetic products are separated by a shaking table and two stage shaker to obtain coarse tin concentrate. Results the tin concentrate containing 9.58% tin was obtained, the recovery of tin was 60.57%, and iron containing 59% was obtained. The iron recovery was 39.21%. The overall index is good, but the iron recovery rate needs to be further improved. The test results can provide the technical basis for the determination of the ore dressing process.
