介绍了山东金岭铁矿近些年来在选矿循环经济发展方面所作的有益探讨。通过加强技术革新改造,逐步形成了“干式预选—多破少磨—湿式预选—高效磁选—高浓度尾矿排放—尾矿、废石充填”具有鲜明技术特色的循环经济发展模式。“清洁化、高效化、资源化”选矿循环经济发展模式的成功实践,促进了企业又好又快发展,在同类铁矿企业中具有较好的推广应用价值。
This paper introduces the beneficial exploration of Shandong Jinling Iron Mine in the development of mineral processing circular economy in recent years. By strengthening the technical innovation and reform, the development mode of circular economy with distinctive technical features has gradually been formed, such as “dry preselection - multiple breakage and less grinding - wet preselection - efficient magnetic separation - high concentration tailings discharge - tailings and waste rock filling” . The successful practice of recycling economy development mode of beneficiation benefited the sound and fast development of enterprises and had a good popularization and application value in similar iron and steel enterprises.
