部分矿石不能回收利用，万群矿段即将闭坑。而金石锰矿另外两个矿区大湖矿段和靳源矿段碳酸锰储量约 40 万 t，品位5.8 15.8%左右，也属于低品位锰矿资源。因此，低品位锰矿的回收利用关系到金石锰矿的生存和发展。 为了解决废弃低品位锰矿的回收问题，企业委托长沙矿冶研究院承担了该矿石的选矿试验研究工作。经过试验研究，通过选用长沙矿冶研究院研制的广义分选空间湿式永磁强磁选机，可以解决该矿的选矿难题，使锰品位提高到 18%以上 ，选矿 指标较好 。 因此，金石锰矿拟建设低品位锰矿回收工程，充分 利用矿山低品位锰矿 资源 ，提高资源综合 利用率，不仅可以 延续企业生产，提高企业 的经济效益，而且符合国家矿产资源综合利用的产业政策，也是 金石锰矿 落实科学发展观，发展循环经济 和参与 “ 两型社会 ” 建设 的一大举措。 1.2 建设条件 1.2.1 资源条件 金石锰矿主矿体万群矿段的 目前还有 低品位锰矿约 60万 t，大湖矿段和靳源矿段 还有低品位 碳酸锰 （ Mn 5.8 15.8%） 储量约 40万 t。这些低品位碳酸锰资源是本次选矿回收工程的资源基础 。
