Question

Odisha is the leading producer of which ore of the following minerals?
A.Iron Ore
B.Manganese Ore
C.Magnesium Ore
D.Tungsten Ore

Answer 1

Let us first know about Ore. Ore is a type of natural rock or silt that includes one or more precious minerals, usually metals, that may be mined, processed, and sold for profit. Mining extracts ore from the earth, which is then treated or processed, usually by smelting, to remove the valuable metals or minerals. The concentration of the desired ingredient in an ore is determined by its grade. The value of the metals or minerals contained in a rock must be balanced against the cost of extraction to determine whether it is of high enough grade to be worth mining and so classified as an ore.

Complete answer:
Manganese is a chemical element with the atomic number $25$ and the symbol $Mn$. It is not found in nature as a free element, however it is frequently found in minerals with iron. Manganese is a transition metal that has a wide range of industrial alloy applications, especially in stainless steels.
Iron ores are rocks and minerals that can be commercially mined for metallic iron. Iron oxides are abundant in the ores, which range in colour from dark grey to bright yellow to deep purple to rusty red. Magnetite ($F{e_3}{O_4},{\text{ }}72.4$ percent $Fe$), hematite ($F{e_2}{O_3},{\text{ }}69.9\% {\text{ }}Fe$), goethite $(FeO\left( {OH} \right),{\text{ }}62.9$ percent Fe), limonite $(FeO\left( {OH} \right)n\left( {{H_2}O} \right),{\text{ }}55{\text{ }}percent{\text{ }}Fe$) and siderite $(FeO\left( {OH} \right)n\left( {{H_2}O} \right),{\text{ }}55$ percent$Fe$) are the most common iron minerals $\left( {FeC{O_3},{\text{ }}48.2{\text{ }}percent{\text{ }}Fe} \right).$
In India, Odisha is the greatest producer of manganese ores. In $2000 - 01$, it accounted for one-third of the country's total output.

Note:
Manganese is a silvery-gray metal with an iron-like appearance. It's hard and brittle, and it's tough to fuse, but it's simple to oxidise. The metal manganese and its common ions are both paramagnetic. Manganese oxidises ("rusts") like iron in water with dissolved oxygen and tarnishes slowly in the air.
