官地银金矿中锰的化学物相分析
Chemical Phase Analysis of Manganese in Silver-gold Ore of Guandi
-
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 pyrolu
