Abstract:
The magnetic changes of the samples prepared from ferrous Wiley Mill have been studied with the economic and fast method of Gouy balance. The results show that the sample was very seriously contaminated by iron, when ferrous content is small in the sample, the error determined is up to 5~6 times. Therefore, a sample prepared from ferrous wiley Mill should not be used to determine the minute iron content in it.
