Through the study on processing mineralogy for a polymetallic sulphide ore containing tin, such factors as the ore material composition, the occurrence of tin, copper, lead and zinc, the crystal morphology, the crystal size and the spatial distribution of multi-elements were analyzed. The processing mineralogy factors which have effect on the recovery of the valuable elements in the polymetallic sulphide ore containing tin were proposed. The research results can provide the optimal mineral processing flowsheet and reference base for the improvement of the recovery of the polymetallic ore,reaching the aim of comprehensive utilization.
