Abstract: On the basis of analyzing the circular economy development modes of the enterprises, it was figured out that the industrial symbiosis pattern is an effective way to develop circular economy in the enterprises. According to current status oflead-zinc industry, it was pointed that it is necessary to construct industrial symbiosis inside the industry. Then in a case study in a lead-zinc smelting plant, the symbiosis relationship, industry linkage, and economic and environmentbenefit were analyzed. The result indicated that constructing the industrial symbiosis pattern in the enterprises could raise efficiency of resources utilization, reduce the pollutant discharge and lower the production cost, thus balancingeconomic benefit and environment protection. Besides, more attention should be paid to the new pollution possibly caused by industrial symbiosis.
