WFC-A物相分析磁选仪测定铁矿石中的磁性铁

Magnetic Iron in Ironstone Determined by WFC-A Phase Analysis of Magnetic Separator

拟定采用自制WFC-A型物相分析磁选仪对铁矿石中的磁性铁进行分离，再用容量法测定磁性铁含量的分析方法，确定该方法的检出限为0.015＆#215;10-2，相对标准偏差为0.42％～4.34％。该方法操作简便、结果准确可靠，为大批量铁矿石中磁性铁的测定分析提供了新途径。

The method introduced in the article is using homemade WFC-A Phase Analysis of Magnetic Separator to separate magnetic iron in ironstone, then uses volumetry to determine the content of magnetic iron, the detection limit is 0.015 ×10-2, relative standard deviation is 0.42%--4.34%. The method is easy to manipulate and the result is reliable. It provides a new way for detecting and analyzing magnetic iron in large quantity of ironstone.
