Kinetics of manganese ore reduction by carbon monoxide
[4-17-2009]
A step has been made in the direction of understanding the fundamental chemical processes taking place inside electric are furnaces producing manganese alloys. The reduction of higher manganese oxides to MnO by carbon monoxide has been studied in the temperature range 700 ¡ãC to 1......

Leaching of manganese from low-grade manganese ore using oxalic acid as reductan
[4-17-2009]
Leaching studies of low-grade Joda manganese ore containing 24.7% Mn and 28.4% Fe were carried out at high temperature and atmospheric pressure using oxalic acid as reductant in sulphuric acid medium. The experiments were designed according to 24 full factorial design, and regres......

Removal of arsenic from groundwater using low cost ferruginous manganese ore
[4-17-2009]
A 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) bei......
