強磁選

錳礦物屬弱磁性礦物〔比磁化系數ｘ＝１０×１０-6～６００×１０-６cm３/g〕，在磁場強度ho＝８００～１６００ka/m（１００００～２００００oe）的強磁場磁選機中可以得到回收，一般能提高錳品位４％～１０％。

由于磁選的操作簡單，易于控制，適應性強，可用于各種錳礦石選別，近年來已在錳礦選礦中占主導地位。

Strong magnetic separation

Manganese was a weak magnetic minerals than the susceptibility [x = 10 × 10-6 ~ 600 × 10-6cm3 / g], the magnetic field strength ho = 800 ~ 1600ka / m (10000 ~ 20000oe) strong magnetic field magnetic separator can be recovered, the general can improve the grade of manganese 4% to 10%.

Due to the simple magnetic separation operation, easy to control, strong adaptability and can be used for a variety of manganese ore sorting, in recent years it has been dominated in manganese ore.
