目前利用氟硅酸钾容量法测定锰矿中二氧化硅含量还没有报道。采用硅氟酸钾容量法,通过称样量、融样方式、酸化体积等条件进行优化实验,实现了容量法快速测定锰矿中二氧化硅的含量。实验数据的相对标准偏差小于1%。测量值与认定值一致,测量结果满足GB/T 1509-2006《锰矿石硅含量的测定高氯酸脱水重量法》允许差的要求。
At present, there is no report on the determination of silica content in manganese ore by potassium fluosilicate capacity method. By the method of potassium silicofluoride capacity, the optimization experiment was carried out by weighing sample, melting sample, acidification volume and other conditions to realize the rapid determination of silica content in manganese ore by volumetric method. The relative standard deviation of experimental data is less than 1%. The measured value is consistent with the certified value, and the measurement result meets the requirements of GB / T 1509-2006 Allowable Difference for Determination of Perchloric Acid Dehydration Weight in Silicon Content of Manganese Ore.
