Abstract: In order to realize the efficient recycling of secondary resources in iron and steel enterprises,the problem of many harmful elements in secondary resources and differences in physical and chemical properties such as particle size,composition,and moisture are addressed.Zhanjiang Iron & Steel conducted research on the secondary resources directly allocated to the sintering production and the research on the production of the solid waste disposal center.When the use ratio of various secondary resources was well controlled,it had little effect on the production of the sinter production and solid waste disposal center.As a result,it is concluded that achieving efficient and comprehensive utilization of secondary resources is conducive to reducing enterprise costs and achieving environmental friendly.

Key words: Secondary resources, Utilization, Harmful elements, Back to production
