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 It is the mainstream method of manganese ore beneficiation. ② The cost of the gravity separation process is much lower than that of the flotation process, and the operation is simple and flexible. 4.

Table 2 shows the concentrations of various metal ions and other water quality parameters present in process water collected from iron ore beneficiation plant followed by settling and filtration. It is observed from the results that the concentration of total Fe, Cr, Pb, Mn and turbidity are found to be 115.24 mg/L, 7.10 mg/L, 2.68 mg/L, 0.96 High-grade manganese ores are mined, crushed and supplied to ferroalloy plants for metallurgical applications. During mining, beneficiation and transportation of these manganese-bearing ores up to 30% of the ore produced is converted into −10 mm low grade Mn ore fines.
