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:

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.
