China 's iron and steel industry generates a huge amount of solid waste , widely distributed, and the comprehensive utilization of the task is arduous . In order to get a clear idea of ??the status of China 's iron and steel industry mainly solid waste recycling technology to provide basic data for its comprehensive utilization . The paper analyzes the major types of solid waste iron and steel industry in China , emissions , origin, distribution , formation process , the basic physical and chemical properties and the integration of these technical approaches and status of solid waste at home and abroad , to identify the constraint on China's iron and steel industrial solid waste the key issues of material resource utilization and specific countermeasures and suggestions . The results show that : the major solid waste produced by the steel industry in China for iron ore waste rock and iron tailings , slag and steel slag , mainly distributed in East China , North China , Northeast and South regions . China 's iron and steel industry solid waste resource utilization in more developed countries ( such as Germany, Japan), there is still a large gap . Restrain China's iron and steel industry solid waste resource utilization , the key question is : (1 ) of the mine waste rock tailings under unclear circumstances , the lack of detailed statistics ; (2) the national and enterprise resource utilization of technology development funds insufficient investment ; ( 3 ) the lack of effective guidance and incentives ; ( 4 ) some enterprises a low level of production technology , discharged slag , slag poor quality ; ( 5) utilization of single structure , the lack of high value-added products ; ( 6) The special nature of the tailings is special, and have yet to find the effective utilization pathway . In response to these problems , it is recommended that : (1 ) The State shall establish special funds , formulating relevant laws and regulations and policies , strengthen the guide and encourage enterprises ; (2 ) the introduction of new technologies, new processes , new equipment and to strengthen the organization and management ; (3 ) research units should focus on developing practical techniques cost a large amount of high slag should realize the industrialization of high - value-added products to strengthen the study of the application of special slag , slag should be the development of new technologies, new processes , new equipment , and to minimize the f - CaO content , enhance its activity , increase the amount of its building materials , while strengthening its research as glass , fertilizer and high value-added products .
