The best working surface touch the ores directly, which have superior magneticfield performance index, thus can get the best magnetic separating results.
工作面直接与矿物接触，工作面磁场性能指标优良，能取得选矿效果；
2
The result matches the designed magneticindex. These provide important theory warranty for setting up pulse high magneticfield.
结果表明，与设计的磁场指标基本相符，对脉冲强磁场装置的实施提供了重要的理论依据。
3
The effects of magneticfield intensity and grinding granularity on magnetic separation index of fe were investigated.
