Manganese nodule occurrence in the Tasman Sea

Abstract Abundant large, discoidal manganese nodules have been recovered at two sites in the Tasman Sea south-east of Sydney. The nodules have todorokite as the main manganese oxide phase, high Mn/Fe ratios (av. 2.5), and moderate concentra-tions of Ni (av. 0.83%) and Cu (av. 0.40%). They therefore have many of the characteristics of nod-

Manganese USGS

Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.

Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and battery material. More than 30 Mn oxide minerals occur in a wide variety of geological settings. They are major components of Mn nodules that pave huge areas of the ocean floor and bottoms of many fresh-water lakes.
