本文通过对矿石的矿物组成,嵌布特性以及物化性质的分析,指出花垣锰矿是一种难选矿石。结合矿石特点及物化性质综合分析了富锰降磷的各种方法优劣之处,提出目前处理该类型矿石的较好方法。重点论述了强磁选—黑锰矿法处理花垣锰矿的基本原理、选别设备、合理流程及工艺影响因素,并对今后试验研究工作提出了看法。
Based on the analysis of mineral composition, inlaid properties and physico-chemical properties of ores, Huayuan manganese ore is a kind of refractory ore. According to the characteristics and physicochemical properties of ores, the advantages and disadvantages of various methods of Mn - rich and P - removal are comprehensively analyzed, and a better method for treating this type of ore is proposed. The paper mainly discusses the basic principle of magnetic separation - black manganese ore processing Huayuan manganese ore, sorting equipment, reasonable process and process influencing factors, and puts forward some opinions on the future experimental research.
