Characteristics and occurrence . Manganese (Mn) is frequently an abundant constituent of soils, but its low solubility at neutral and alkaline pH prevents excessive uptake by plants. Therefore, manganese toxicity is nearly always associated with acid soils.Waterlogging may also induce or exacerbate manganese toxicity, as anaerobic conditions cause higher oxides of manganese

Mineral Resource of the Month Thallium. David E. Guberman, According to the company, the deposit is unique because it is the only known occurrence of thallium with cobalt and manganese. The feasibility of economic production of thallium from the site has not yet been confirmed.
Occurrence of Manganese in Drinking Water and Manganese Control describes the chemistry and suggested treatment of manganese in drinking water, with the goals of reducing customer complaints and improving perceived water quality.
Manganese is very similar to iron in chemistry and in the way it is distributed and concentrated in rocks. Such is the case because manganese, like iron, has two important valence states, Mn 2+ and Mn 4+.In the +2 state, manganese forms soluble compounds Occurrence, uses, and properties

Todorokite is a rare complex hydrous manganese oxide mineral with the formula (Na,Ca,K,Ba,Sr) 1x (Mn,Mg,Al) 6 O 12 183;34H 2 O. It was named in 1934 for the type locality, the Todoroki mine, Hokkaido, Japan.
Mar 03, 20110183;32;Manganese is a trace element and eating a small amount from food or water is needed to stay healthy. Exposure to excess levels of manganese may occur from breathing air, particularly where manganese is used in manufacturing, and from drinking water and eating food. At high levels, it can cause damage to the brain, liver,

Distribution of Manganese in India Manganese is an important mineral, which is used for making iron and steel and it acts as basic raw material for manufacturing its alloy. Nearly 10 kilograms of manganese is required for manufacturing one tonne of steel.
The manganese ores of these districts in composition and mode of occurrence are closely related to Gondite type (Madhya Pradesh, India) of a definite metamorphic origin  . The ores in question and also the manganese ores of Gondite type (M.P.) contain braunite, jacobsite, bixbyite, spessartite and rhodonite with their own peculiarities.

Natural nuclear fission reactors time constraints for occurrence, and their relation to uranium and manganese deposits and to the evolution of the atmosphere
Manganese has also exhibited efficiency in controlling the level of sugar in the human blood. This may further prevent the occurrence of certain diseases like diabetes.
Manganiferous rocks are found in two areas in eastern Aroostook County, Maine, one west and northwest of Presque Isle and the other south of Houlton. The manganiferous deposits are sedimentary lenses, up to 150 feet thick and half a mile long, in middle Silurian argilllte. The rocks of both areas are much deformed, but the deformation is less intense and the continuity of the deposits
Manganese Manganese is widely distributed in the terrestrial crust. It is usually associated with the iron ores, in relatively small concentrations. The principal manganese ores
Pyrolusite is the most common manganese mineral and is an important ore. Manganese is a strategically valuable metal since it is an essential ingredient in steel and other alloys. The mining term quot;wadquot; is used to indicate ores that are a mixture of several manganese oxides such as pyrolusite, psilomelane and others that are
Since manganese (Mn) was established as an essential element for plant growth, much progress has been made in our ability to recognize and predict the occurrence of Mn deficiency in plants, and to devise suitable corrective measures (74, 97, 98).
