Why is graphite slippery?
The delocalised electrons are free to move through the structure, so graphite can conduct electricity. … The layers in graphite can slide over each other because the forces between them are weak. This makes graphite slippery, so it is useful as a lubricant .
Which state is largest producer of mica?
Mica deposits mainly occur in Jharkhand, Bihar, Andhra Pradesh and Rajasthan. India is the largest producer and exporter of mica in the world.
Which is the richest state in minerals?
ChhattisgarhChhattisgarh is one of the most important mineral rich States inside the country. Twenty-Eight known varieties of minerals are found in the State including valuable stones & diamonds, iron ore, coal, limestone, dolomite, tin ore, bauxite and gold.
Which state is richest in mineral production?
Jharkhand carved out of Bihar in November, 2000 is one of the leading mineral producing States. It is one of the leading producers of coal, kyanite, gold, silver, bauxite and felspar.
Where in India graphite is found?
Graphite occurrences are reported from various states but the deposits of economic importance are located in Andhra Pradesh, Jharkhand, Karnataka, Kerala, Odisha, Rajasthan and Tamil Nadu.
Where is graphite found naturally?
It also occurs in igneous rocks and in meteorites. Minerals associated with graphite include quartz, calcite, micas and tourmaline. The principal export sources of mined graphite are in order of tonnage: China, Mexico, Canada, Brazil, and Madagascar. In meteorites, graphite occurs with troilite and silicate minerals.
Where is graphite mined in the US?
Graphite is deemed a critical material by the US, and about a century ago it was mined abundantly in the country, mostly in Alabama.
Why is graphite dangerous?
Excessive exposure to graphite dust over extended periods of time can cause a chronic and more serious condition known as Graphitosis, which is a form of pneumoconiosis. This condition arises when inhaled particles of graphite are retained in the lungs and bronchi.
Is graphite hard or soft?
Graphite is very soft and slippery. Diamond is the hardest substance known to man. If both are made only of carbon what gives them different properties? The answer lies in the way the carbon atoms form bonds with each other.
Why is graphite black?
By contrast, graphite is a conductor. As a conductor, it has electrons in the conduction band already. … And since electrons will absorb any amount of energy easily, the material absorbs all wavelengths of light: which makes it black.

What mineral is graphite?
Some of the world’s greatest art was rendered in graphite, a mineral composed solely of the element carbon. Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling.
How is graphite formed?
Graphite is formed by the metamorphosis of sediments containing carbonaceous material, by the reaction of carbon compounds with hydrothermal solutions or magmatic fluids, or possibly by the crystallization of magmatic carbon.
Where is Diamond found?
Relation to Mining Natural diamond has been discovered in 35 countries. Some diamonds have been found in the United States. Colorado, for instance, has produced a small number of diamonds. The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa.
Is nuclear graphite dangerous?
There have been two major accidents in graphite-moderated reactors, the Windscale fire and the Chernobyl disaster. In the Windscale fire, an untested annealing process for the graphite was used, causing overheating in unmonitored areas of the core and leading directly to the ignition of the fire.
Which state is the largest producer of lead in India?
RajasthanADVERTISEMENTS: Rajasthan is the leading producer. In 2002-03 this state produced 55.8 thousand tonnes of lead which accounted for over 94 per cent of the total production of India. Udaipur (Zawar, Rikhabdeo and Debari), Dungarpur (Ghughra and Mando), Banswara (Wardalia) and Alwar are the main producing districts.
Where is graphite most commonly found?
ChinaWhere is Graphite Sourced. China is the largest exporter producing 75-80% of the world’s graphite. There are numerous other countries including Canada, India, Brazil, Sri Lanka and North Korea.
How common is graphite?
Graphite is rather common mineral, but fine crystals are rare. Most Graphite mining areas produce enormous quantities from a single or several large Graphite veins, but collector specimens in good crystals are not commonly encountered.
Can graphite be harmful?
Graphite is relatively nonpoisonous. There may be no symptoms. If symptoms do occur, they may include stomachache and vomiting, which could be from a bowel obstruction (blockage). The person may choke while swallowing the pencil.
Is graphite used in pencils?
False. Lead pencils contain graphite (a form of carbon), not lead. In fact, contrary to what many people believe, lead pencils never were made with lead. The ancient Romans used a writing device called a stylus.
