摘要: 从工艺矿物学的角度分析了某含银多金属锰矿实现锰、银分离的难点,参照类似性质矿石的处理工艺,并结合研究对象的性质特点,指出其合适的开发利用工艺为干式筛分分级—粗粒干式强磁选—细粒湿式强磁选—混合精矿湿法冶金浸出。通过实验室试验,最终获得锰品位31.59%、银品位657.9 g/t、铁品位11.72%,锰回收率90.24%、银回收率91.29%、铁回收率78.51%的混合精矿,为大规模、高效率、低成本开发利用该矿石奠定了基础。

Abstract: The paper analyzed the difficulties in separation of Manganese and Silver for a silver-bearing multi-metal manganese ore from the angle of process mineralogy. With a reference to the process mineralogy study of similar ores, and combining with the nature of this ore, one suitable process is proposed, which consists of dry screening classification-dry coarse high intensity magnetic separation-wet fine high intensity magnetic separation-mixed concentrate wet leaching.Through the laboratory tests, a mixed concentrate grading at 31.59% of manganese, 657.9g / t of silver, 11.72% of iron with a Mn recovery of 90.24%, Ag recovery of 91.29%, Fe recovery of 78.51% were achieved respectivelyThis process provides a basis for large scale, high-efficiency and low cost production of similar ores.
