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

If the main gangue in nickelcopper 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.Details
