Manganese is a critical trace element. Manganese seems to lend a pliant, flexible quality to animal bone. A manganese deficiency in bone leads to brittle, easily broken bones. Manganese also activates several important enzymes, assists in the functioning of metabolism, and aids in the utilization of Vitamin B1.
Mineralogy. In general common rock forming minerals do not contain significant amounts of cobalt. However, it can be found in economic concentrations in olivine, spinel and chloride in lateritic and hydrothermal deposits (hydrothermal deposits occur where

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining ; they are then refined (often via smelting ) to extract the valuable element or elements.

Manganese ores is confined to different rock types, belonging to both Khondalite and Charnockite groups, where they are dispersed throughout the country rocks as small lenses, pockets, veins and irregular bodies of varying dimensions. Quartz, garnet, clay, limonite and apatite are the common gangue minerals in the Manganese ores.
The commercially important manganese ore deposits are ordinarily of secondary origin that is; they are concentrated by weathering from manganese minerals more sparsely distributed in rocks. In igneous rocks manganese is always present but only in small amounts. The largest percentages (about 0.36 percent.) are found in syenite and its porphyries and in basalt. Sedimentary rocks may contain
Manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 176;C (2,271 176;F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such
Manganese ore is mined in the Black Rock area of the Kalahari, in the Northern Cape Province. The majority of the production is intended for export, but a portion is supplied within the Group to Cato Ridge Works in KwaZulu Natal, and to the domestic market.

The structure is massive, but concretions of pyrolusite may be present. ii) The intermediate ferruginous manganese zone consists of psilomelane, pyrolusite and hematite with up to 15% goethite, quartz, barite, and clay minerals.
quot;Rock of the Month 157, posted for July 2014quot; Manganese ore. from the Kalahari manganese field. The Kalahari manganese field in Northern Cape Province, South Africa, hosts the world's largest manganese ore resources, beneath an area of at least 1,100 km 2.The ores are the largest land based sediment hosted manganese resource known.
The rst of these features results in manganese enriched sedimentary rocks (manganese deposits, commonly Mn ore deposits), which generally correspond to the availability of molecular oxygen in Earth surface environments.

Manganese rock by composition is represented by two subgroups of the chemical and biochemical group of sedimentary rocks (Frolov, 1964a,b)carbonate and oxide (manganolites). Manganolites represent sedimentary rocks and ores, the predominant component of which are oxides and hydroxides of manganese (Geologicheskii slovar, 1973.

Manganese. Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels .
The Kalahari Manganese Field, located in Northern Cape Province, about 700km southwest of Johannesburg, contains around 80% of the worlds known high grade manganese ore reserves. The district yields about 4Mtpa, mined mainly by two companies Samancor and Assmang.
