Abstract:In non-ferrous metal mine engineering, because the waste water produced in the process of beneficiation contains residual beneficiation agents, which causes serious pollution to the environment, so the design of water supply and drainage system is more and more important for the construction of concentrator. Water balance is mainly introduced in this paper, the classification of the water system, the choice of process water, waste water pool, water pumping stations, high production design principle, and according to the specific links and points of water supply and drainage design of concentrator has carried on the thorough analysis, put forward some scientific design methods, in order to provide references for water supply and drainage design of concentrator
