In INDIA we have huge dumps of low grades from 20 to 40%. Example 25, 25, 25 MnO2, SiO2, FE2O3 --how to upgrade, and to what extent!Does anyone have experience in floating Manganese dioxide and what Chemicals are used.

Have you looked at:

"beneficiation of low grade manganese ore fines"?

Historically, methods used are gravity, magnetic and dense media separation. MnO is relatively dense and usually the problem is ferruginous matter. Could you please elaborate further?

I do have experience in what you say. Today we are looking for waste management and low grade processing. Many free silica and silicates are there in low grade ores. I know how to float Free Silica, through column flotation but I heard that even MnO2, MnO can be floated. If it is so we can produce 70% grade which has 100 demand and market for huge profits in Rs 6lakhs/ton -$ 1 lakh per ton.

We have developed Cacination furnaces for producing Mno, trying for electrolysis process too for Mnso4. Today low grade ores pose problems for pollution, and economics.
