Physical separation of iron ore: magnetic separation - ScienceDirect

2022年1月1日  While magnetite ores are naturally suitable for magnetic separation, oxidized iron ores are much more difficult to recover using magnetic separation due to the magnetic susceptibilities of their iron minerals, which are only about 1% of that for
