Beneficiation of low grade manganese ore fines
manganese ore is usually hand sorted into lump ore and fines. The manganese content in the lump ore is higher compared to that of the fines. At present, the manual sizing and sorting of manganese ore practised in India give an yield of about 30 to 55 per cent of saleable manga-nese ore from the r•o.m. ore and the ore fines
