Interesting facts about the minerals we transport:
What is coal?
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variables amounts of other elements chiefly hydrogen, sulphur, oxygen and nitrogen.
What is the use of coal?
The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal- also known as thermal coal is mainly used in power generation.
What is chromite?
Chromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinal group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite.
What is chrome mineral used for?
The chromium extracted from chromite is used in chrome planting and alloying for production of corrosion resistant, super-alloys, nichrome and stainless steel. Chromium is used as a pigment for glass, glazes and paint and as an oxidizing agent for tanning leather.
What is iron ore?
Iron ore are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxide and very in colour from dark greys, bright yellow or deep purple to rust red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite.
Use of iron ore:
The primary use of iron ore is in the production of iron. Most of the iron is used to make automobiles, locomotives, and ships, beams used in buildings, furniture, paper clips, and tools, reinforcing rods for concrete, bicycles, and thousands of other items.
What is oil?
An oil is a nonpolar chemical substance that is viscous liquid at ambient temperatures and is both hydrophobic and lipophilic. Oils have a high carbon and hydrogen content and are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.
What is oil used for?
Oil and gas are used widely in modern life. Oil fuels the cars, trucks and planes that underpin modern economies life styles. By-products from oil refining are used in the production of plastics and chemicals, as well as many lubricants, waxes, tars and asphalt.
What is fuel?
A material such as coal, gas or oil that is burnt to produce heat or power. A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work.
What is fuel used for?
A power plant using a fuel to make electricity. Almost all power plants rely on some type of fuel (instead of a primary energy flow) as a source of energy. Fuels are dense Repositories of energy that are consumed to provide energy services such as heating, transportation and electrical generation.
