Indian Manganese Ore Industry & Scope for its Development

Abstract

In this short paper are reviewed the reserves of Indian manganese ores and their quality. Emphasis has been laid on different possibilities of their exploitation for the manufacture of ferro-alloys in this country and export of the latter in preference to that of raw unprocessed manganese ores. Mineral upgrading by ore-dressing methods of low-grade manganese ores has been referred to, followed by the possibilities of their thermal beneficiation for the production of ferro-manganese. In this connection the efforts of countries deficient in manganese mineral to tap all possible sources of manganese,such as recovery from steel slags, manganiferous iron ores, etc., have been discussed.
