Influence of Mineralogy on the Dry Magnetic Separation of ...

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to …

Ore for Mn/Fe Beneficiation: Morphology Evolution and ...
