锰矿石中钙镁测定的研究

Research on the calcium and magnesium determination in manganese ores

通过实验建立了用H2O2-DDTC一次分离,EDTA容量法测定富锰试样中CaO和MgO的方法,指出在试样中加入H2O2,在近中性的条件下煮沸沉淀大量Mn,当分解近完全时加入DDTC沉淀少量Mn和杂质后,用EDTA滴定,该方法简便快速,应用于锰矿和锰铁渣样中CaO和MgO的冶金快速分析,取得了较好的效果。

Through the test built the method using H2 02-DDTC a separation, EDTA volumetric method determination of CaO and MgO rich of manganese, pointed out adding H2 02 in samples, after boiling deposits large Mn near neutral conditions, adding small amount of Mn and impurities when the complete decomposition, using EDTA titration, the method was simple, the rapid metallurgy analysis on CaO and MgO applied in manganese ore and slag samples, achieved good results.
