Removal of Magnesium Oxide from High MgO Content Ores ...

If the main gangue in nickel-copper sulfide ores or precious metals sulfide ores is serpentine transformed from primary silicate minerals, it is difficult to get a high quality concentrate with lower MgO content that is suitable for smelting by physical mineral processing only such as floatation. This thesis put forward a new method to process this kind of ores.
