We report the Mossbauer study on seven samples obtained from the different stages of artificial rutile producing processes by two technological methods. The first method is the oxido-reduction treatment for the leaching ilmenite sample in the hydrochloric acid（HCl） and the second one is the leach of original ilmenite sample directly in HCl. Measuring the ratio Fe 2+ /Fe 3+ by Mossbauer effect, it is found that the first method is much better than the second one. 穆斯堡尔效应 金红石 钛铁矿 矿物学 Mossbauer effect ruffle ilmenite mineralogy O571.23 1993-03-01 2021-04-01 3
