How can I separate magnetite from magnetite and hematite mixture?

09 August 2024 0 909 Report

From a natural rock sample I have separated the magnetic minerals using hand magnet first. Then I have grinded them to approx. 200 mesh. This mixture contains magnetite and hematite in different proportion. I wanted to separate these two minerals. Using hand magnet I am unable to do that as it is attracting both the minerals. I have tried to do that with Frantz iso dynamic separator, but the channel is getting clogged again and again.

Can someone help me with any suggestion or something for this problem?
