    1.1. Manganese Ore Deposits. Over 80% of the known world, manganese resources are found in South Africa and Ukraine. Other important manganese deposits are in China, Australia, Brazil, Gabon, India and Mexico. The economically mineable manganese deposits are in natural concentrations of 150 - 500 times the average crustal abundance.

    Manganese Ores. Some manganese minerals and mineraloids are considered “primary ores,” because they are rich enough in manganese to be of ore grade. Others are “secondary ores.” These occur in zones where the original manganese content of the sediments has been naturally enriched by younger geologic processes.

    The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production. The U.S., Japan, and Western Europe are all nearly deficient in economically mineable manganese. South Africa and the Ukraine have over 80% of the world’s reserves.

    Nov 08, 2020 The average manganese recovery in this operation is usually between 60% and 75%. Metallurgical grade manganese ores contain typically 40% to 50% manganese. Another important parameter is the manganese-to-iron ratio (Mn/Fe), which is required to be 7.5 by weight for the production of standard ferromanganese alloy with 78% Mn.
