Manganese: Introduction

Manganese: Introduction

Pyrolusite is the oxide ore of manganese. It is the most important ore mineral of manganese. The oxide ores are mostly found in sedimentary deposits. In the sedimentary rocks, the manganese oxides precipitated in beds as manganese nodules. Manganese ore is also found deposited with iron ores. Some of the manganese deposits are formed by leaching of manganese oxides from silicate minerals

Manganese Ore - an overview | ScienceDirect Topics

Major compounds of manganese, such as manganese dioxide (MnO 2) or potassium permanganate (KMnO 4), are used as depolarizers in the battery industry or as oxidation, bleaching, and disinfection agent. Most of the manganese ores (with 30–55% Mn) are mined in Ukraine, China, South Africa, Brazil, Gabun, India, and Georgia. Large amounts of manganese can be found in marine manganese nodules

Manganese ore containing 20% or more manganese has not been produced domestically since 1970. Manganese ore was consumed mainly by six firms with plants principally in the East and Midwest. Most ore consumption was related to steel production, either directly in pig iron manufacture or indirectly through upgrading the ore to ferroalloys
