摘要
将高铁赤泥与焦炭按照一定比例混合在马弗炉中进行高温磁化,磁化后物质加入分选剂用磁选机进行湿法磁选。经研究发现,分选剂烷基磺酸钠和硅胶联合作用,能够将磁性物质和非磁性物质有效分离,显著提高磁选铁精矿的品位,提高了磁选效率。
Iron-rich red mud is added to separating agents to separate magnetic materials after it is magnetized with certain char in high temperature. It is shown that the grade of iron ore concentrate is improved greatly by using separating agents of alkyl sodium sulfonate and silica gel, which make a high separating efficiency.
