贵州某低品位碳酸锰矿工艺矿物学及选矿试验研究

Experimental Study on Process Mineralogy and Mineral Processing of a Low-grade Manganese Carbonate Ore in Guizhou

贵州某锰矿储量大、品位低,为使该矿得到合理开发利用,本文通过化学分析、物相分析、扫描电镜、X射线分析和MLA等方法进行了系统的工艺矿物学研究,在此基础上制订出适合该矿的选矿工艺流程,在原矿含Mn9.52%条件下,通过一粗一扫强磁选,可得到锰品位15.56%,回收率85.54%的良好指标,为该矿的高效利用奠定了技术基础。

Aiming at the characteristics for low-grade and rich- reserves in a manganese from Guizhou in order to make a reasonable development and utilization of the mine, the process of mineralogy was studied by chemical analysis, phase analysis, scanning electron microscopy, X-ray analysis and MLA, to develop a suitable for the ore dressing process. Under the conditions of Mn 9.52% in the raw ore, the results were obtained as follows： manganese content in manganese concentrate is 15.56% and recovery is 85.54%, which laid the technical foundation for the efficient use of the mine.
