酒钢镜铁山铁矿分为桦树沟和黑沟两大矿区,前者为井下矿,后者为露天矿,两者的矿物组成、结构构造及选矿参数均有较大差异,但却进入相同的工艺,采用相同的参数进行选别,造成生产技术指标不是最佳。通过对两种粉矿的矿石性质及可选性进行对比研究,查明其差异,并确定各自适宜的磨矿、选别等工艺参数,为进一步改善精矿质量、提高资源利用率提供依据。
Jiuquan Steel Tieshan Iron Mine is divided into two major mining areas, namely Bingshugou and Heigou. The former is a downhole mine and the latter is an open pit mine. The mineral composition, structural structure and ore dressing parameters of the two are quite different, but they enter into The same process, using the same parameters for sorting, resulting in the production of technical indicators is not the best. By comparing the properties and the selectivity of the two kinds of ores, the differences were identified, and the appropriate parameters of grinding, sorting and other processes were determined, which provided the basis for further improving the quality of concentrates and improving the utilization rate of resources.
