Abstract
Manganese ores of Koraput district are typically found in Nishikhal area and occur in association with the khondalite suite of rocks. The manganese ore is high grade in quality with Mn — 59 to 64%. The ores have high phosphorous content, P — 0.30%. The important ore minerals are psilomelane, pyrolusite, braunite, cryptomelane and goethite. Bixbyite, nsutite, hollandite, rhodochrosite and manganite are detected by X-ray. These ores are residual concentration type and suggest enrichment by supergene processes.
