Abstract: This article describes the current situation on the domestic comprehensive utilization about Mine tailings.According to Qi Liuzai alluvial tin tailing mining technology,then choose the surface mining methods to stop tailing.Excavation of working face to drying one week to continue excavation to solve the problem of the exposured and easy to collapsed and difficult to form bench face in mining exploitation.Mat stone or laying polyethylene sheet to solve the problem of the mining and transport equipment into the tailing.Tailings sorting using the following procedure:Grade tailing by hydrocyclone,Grit by magnetic and gravity separation,Fango beneficiation by gravity.Due to the selected tailings contained too much mineral mud lead to premature settlement is difficult to form a suitable pulp density,blockaged tube and ditch.Get success by taking 20 to 25 percent into the sand tin oxide ore,tin ore or veins to be successful,the final output of qualified products - middling product tin.
