摘　　要：本文报道用还原焙烧－氨浸法处理遵义锰矿高铁贫锰重选尾矿石的试验结果．该产品可供生产中低碳锰铁、金属锰及开发锰盐新产品作原料．产品成本经估算约为９５４元／ｔ．本试验为我国高铁贫锰矿的湿法提锰提供了一条新的途径．Test results of treatment of high iron and low manganese contained tailingsfrom the gravitational separation of Zun Yi manganese ore,by a reducing roast-annmonia-cal leaching process are reported.The products can be used as raw material for producingferromanganese with contents of medium or low carbon,manganese metals and compounds.The cost for the products is approximately RMAY 954 per metric ton as estimated.The testprovides a new process for hydrometallurgically extracting manganese from domestic oreswith contents of high iron and low manganese.
