Jan 21, 2015 · Manganese is a naturally occurring substance found in many types of rock. Manganese does not have a special taste or smell. Pure manganese is a silvercolored metal however, it does not occur in the environment as a pure metal. Rather, it occurs combined with other substances such as oxygen, sulfur, and chlorine. These forms (called compounds) are solids that do not evapoï¿½rate.
In Mexico and elsewhere there are large bodies of valuable silver ore containing manganese which present great, and hitherto insuperable, obstacles to a satisfactory extraction by cyanide. The proportion of the silver that is soluble in cyanide varies greatly and may be as low as 5% only. The mere presence of manganese in the ore is not invariably accompanied by refractoriness of the silver

Manganese(IV) oxide is the inorganic compound with the formula MnO 2.This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules.The principal use for MnO 2 is for drycell batteries, such as the alkaline battery and the zinccarbon battery. MnO 2 is also used as a pigment and as a precursor to other manganese
Manganese deficiency is rare but can be expressed in poor bone health, joint pain, fertility problems, and an increased risk of seizures. Overconsumption of manganese from food sources is also rare and can adversely affect the neurological system. Foods high in manganese include mussels, wheat germ, tofu, sweet potatoes, nuts, brown rice, lima
Exposure to manganese dust occurs primarily in mining, orecrushing, and metallurgical operations for iron, steel, ferrous and nonferrous alloys. Manufacturing of drycell batteries, antiknock gasoline additives, pesticides (e.g. maneb), pigments, dyes, inks and incendiary devices can also lead to occupational manganese exposure.
