Upgradation of Low-Grade Siliceous Manganese Ore …
Three varieties of low-grade Mn-ore such as a) siliceous, b) ferruginous and c) aluminous types have been reported from this belt (1). Over the last few decades, selective mining of better grade manganese ores from this area has generated a huge quantity of low/off grade ores, which are considered as waste. Stacking of such ores near

characterized as ferruginous- and siliceous-type ores. The ores are mostly high grade, soft and friable in nature, with minor quantities of hard lumpy ore in separate bands. These are mainly associated with laterite, altered ultramafic rock, nickel ferrous limonite, goethite, and talc-serpentine schist.
