The dephosphorization of a manganese oxide concentrate with an increased phosphorus content is experimentally studied by blowing a manganese-containing melt with carbon monoxide in the temperature range 1400–1560°C. The reaction of gaseous carbon monoxide with phosphorus oxide dissolved in a manganese-containing melt begins to develop. The dephosphorization leads to a substantial decrease in the phosphorus content in a manganese-containing melt. A new method for the dephosphorization of manganese-containing products is developed. The method has no analogs and makes it possible to involve domestic manganese ores in production.

国内锰矿石参与生产

通过在1400-1560°C的温度范围内用一氧化碳吹入含锰的熔体，对磷含量增加的氧化锰精矿的脱磷进行了实验研究。气态一氧化碳与溶解在含锰熔体中的氧化磷的反应开始发展。脱磷导致含锰熔体中磷的含量大大降低。开发了一种用于含锰产品脱磷的新方法。该方法没有类似物，可以将国内锰矿石用于生产。
