| 摘 要： | 根据官地银金矿中锰矿物的共生组合情况，引用Al（NO3）3溶液作碳酸锰矿物的选择性溶剂，H2SO4-KF-HF混合溶液作水锰矿、褐锰矿的选择性溶剂，于滤渣中测定软锰矿（包括少量硅酸锰矿物）。实验表明，所引方法适用于官地银金矿区锰矿物的相态分离，所得结果与外检结果一致，满足了矿床划带的实际需要。

| Abstract: | Based on the characteristics of paragentic manganese minerals in silver-gold ore of Guandi,the chemical phase separation selective solvents of Al(NO_3)_3 was chosen for manganese carbide phase and H_2SO_4-KF-HF for manganite and braunite phases.The pyrolusite(including a few manganous silicate minerals) in the filtrates was determined after phase separation.The results were in agreement with those from external examination.The method can satisfy the practical demands for zoning of ore deposits. |
