The formula of the brown oxide of manganese is MnO2.Manganese dioxide is the inorganic compound is the blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese.
In ancient times, two black minerals from Magnesia (now Greece) were both called magnes but was thought to differ in gender. The male magnes attracted iron(the iron ore we know as magnetite. which probably gave us the term magnet) but the females didn't. In the 16th century. the compound was called manganesum. Then later isolated to the term manganese.
It is mined, and extracted from: * pyrolusite (MnO2), * braunite (Mn2+Mn3+6SiO12), * psilomelane (Ba(Mn2+)(Mn4+)8O16(OH)4), and * to a lesser extent as rhodochrosite (MnCO3). The ore is processed similarly to iron ore to make steel, but requires higher temperatures.

DMTU means dry metric tonne unit. A 'unit' is 10kg, or 1 tonne divided into 100 units.Essentially USD3.60 per dmtu is equal to USD360 per tonne of pure manganese metal.This pricing structure is commonly used for manganese ore sales (as opposed to pure manganese metal). A typical manganese ore would grade 45% Manganese so a price per tonne of this 'impure' ore would be 45% of USD360 per tonne = USD162 per tonne.More refined ferro-manganese products will command a higher price than the basic manganese ore.

the cost per ton of manganese ore out of India? 80 yuan / ton degrees
DMTU means dry metric tonne unit. A 'unit' is 10kg, or 1 tonne divided into 100 units. Essentially $8/dmtu is equal to $800/tonne of pure manganese metal. This procing structure is commonly used for manganese ore sales (as opposed to pure manganese metal). A typical manganese ore would grade 45% Manganese so a price per tonne of this 'impure' ore would be 45% of $800/tonne = $360/tonne. More refined ferro-manganese products will command a higher price than the basic manganese ore.

Manganese is non renewable because it is an element. It is widely distributed in the Earth's crust usually mixed with other things so there is no danger of running out of it. The principle ore is Manganese dioxide MnO2
