Percolation Leaching of Manganese Ore by Aqueous Sulfur Dioxide
[12-21-2007]
The sulfite leaching of an Italian Mn ore has been carried out to determine the feasibility of extracting Mn by percolation leaching. Aqueous SO sub 2 has been found to be an effective leachant for Mn dissolution owing to fast dissolution kinetics and low temperatures. Benc......

Removal of arsenic from groundwater using low cost ferruginous manganese ore
[12-21-2007]
low cost ferruginous manganese ore (FMO) has been studied for the removal of arsenic from groundwater. The major mineral phases present in the FMO are pyrolusite and goethite. The studied FMO can adsorb both AS(III) and As(V) without any pre-treatment, adsorption of As(III) b......

Studies on reaction mechanism of bioleaching of manganese ore
[12-21-2007]
A systematic study has been made to establish the reaction mechanism of bioleaching of manganese ore with the manganese reducing fungi, Penicillium citrinum, isolated from the top soil of an active manganese ore mine site. The fungi was utilised for dissolution of manganese......
