Abstract: A tin ore of complex composition is from Yunnan province, with rich valuable metals, and valuable minerals mainly exists in form of skarn & skarn—sulphide ore type which are finely disseminated. Although after flotation—gravity concentration—flotation—magnetic separation treatment, there are also valuable minerals in the ore. Economic benefits was achieved through comprehensive recycling and utilization of the ore by gravity—magnetic combined separation process.

Key words: Tin tailings, Flotation, Gravity—magnetic combined separation process
