In this paper, a stepwise magnetic.
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 understand the influence of.
In the testing process, we found that the materials were partially melted at a temperature of 1100 C, and the material was already in the melted state at a temperature of 1200 C. Further , the segregation roasting ores will be difficult to grind and affect the recovery of nickel and iron in the magnetic separation process.
