the analysis and determination of barium oxide ores usually by gravimetric method of barium sulfate, lead chromate capacity method and EDTA volumetric method for the determination of lead, for the mineral, lead chromate capacity method is not suitable. This paper proposed the lead-zinc mine, iron ore, barite and rock in more than 1% of barium oxide EDTA capacity titration method, rapid, accurate, the.end point of titration jump significantly, with corundum crucible instead of platinum crucible sample-smelting, is easy to popularize.
