- Enrichment Of Manganese Ore
Attempts were made to enrich manganese content as well as Mn/Fe ratio from a complex manganese ore from Nishikhal deposit, Orissa, India, containing 32% Mn, 18% Fe, 16% SiO 2, 21% acid insolubles and 0.45% P by reduction roasting followed by magnetic separation route. Interestingly the adopted route not only enriched the Mn content to …

In the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO2, with a manganese-to-iron mass ratio (Mn:Fe ratio) of 1.6. This ore was characterized in detail using …
