Status and color of Manganese metal.

3. Johan Gottlieb Gahn, a Swedish chemist and mineralogist, succeeded in isolating this metal from pyrolusite in 1774.

4. Manganese is the twelfth most abundant element in the Earth's crust with 0.1% by weight. The manganese abundance in our solar system is 10 parts per million by weight.

5. Manganese is an essential trace element for all life on earth and is important in photosynthesis. Without manganese, there would be no free oxygen on earth.

Some foods contain high levels of Manganese.

6. Manganese is essential for the manufacture of iron and steel because of its sulfur fixation, deoxidation, and alloying properties. Although manganese is too brittle to use for its own structure, alloying with manganese iron produces a steel with improved rolling and forging qualities, strength, toughness, rigidity, ability abrasion resistance, hardness and hardening ability. It also helps to remove sulfur and oxygen contaminants from molten steel.

7. An adult will have a total of about 12 mg of manganese in the body.

8. Manganese becomes life-threatening when exposed to the limit or above 500 mg / m 3.
