摘要
目前钒钛磁铁矿中磁性铁分析尚无国家标准,大部分实验室一直都是采用手工磁选法测定磁性铁的含量,但精密度及准确度均较差,还有部分实验室采用磁选仪进行磁选分析,精密度有所提高,但是测试结果仍偏低。因此,建立一套科学、准确、快速的钒钛磁铁矿分析技术至关重要。
At present,there is no national standard for the analysis of magnetic iron in vanadium-titanium magnetite.Most laboratories always use manual magnetic separation method to determine the content of magnetic iron,but the precision and accuracy are poor.Some laboratories use magnetic separator for magnetic separation analysis,the precision is still good,but the test results are still low.Therefore,it is very important to establish a set of scientific,accurate and fast vanadium-titanium magnetite analysis technology.
