随着矿山生产的不断深入,矿产资源的有效利用对于矿山的长远发展显得尤为重要。通钢集团板石矿业公司在保证主矿体正常开采的同时,更注重综合利用的整合开发,即对排碴场中的铁矿石进行磁选回收项目将越来越被矿山企业所重视,整合开发的力度将会逐步加大,磁选矿石也将成为未来原矿来源中不可或缺的一部分。在此之前,该公司对磁选矿石的采制样没有真正去实际接触,更没有这方面的相关资料和实际经验可供参考与借鉴,只能按原矿采制样操作规程进行。由于磁选矿石粉矿含量较大,而且块状矿石粒级不同,品位波动也较大,在制样过程中试样无法达到充分混
With the deepening of mine production, the effective use of mineral resources is particularly important for the long-term development of mines. Tonghua Steel Group slab mining company to ensure the normal exploitation of the main ore at the same time, pay more attention to the integrated utilization of integrated development, that is, the excavated field of iron ore magnetic separation recovery project will be more and more mining enterprises attach importance, Integrative development efforts will gradually increase the magnetic separation of ore will also become an integral part of the future of ore sources. Prior to this, the company did not have any real contact with the magnetic separation ore samples, nor did it have relevant information and practical experience in this respect for reference and reference. It can only proceed according to the original ore sampling procedures. Due to the large content of magnetic separation ore powder ore, and the different size of lump ore, grade fluctuations are also large, the sample preparation process can not be fully mixed
