摘要
将铁矿石试样用NaOH+Na2O2混合熔剂分解,再用稀盐酸浸取,使硅成硅酸状态,然后采用硅钼蓝分光光度法测定二氧化硅的含量。该方法简便、准确、可靠,实现了铁矿石中常量硅的快速测定,能够很好地适应选矿过程控制的需要。
The iron ore sample is decomposed with NaOH＋ Na2O2 flux and the melt is digested with dilute hydrochloric acid to convert the SiO2 into soluble silicic acid. Then the silicon dioxide content in the sample is determined by molybdenum-blue spectrophotometry. The method that is simple, accurate and reliable enables a rapid maeroanalysis of silicon dioxide, well meeting the control requirement of iron ore beneficiation.
