Ore

Ore

An ore is a special type of rock that contains a large enough amount of a particular mineral (usually a Metal) to make it economically practical to extract that mineral from the surrounding rock. Not all Minerals are found in a large enough amount in one location to make it worth it to remove the ore from the rock through a process known as mining. Ores can be mined in a number of ways, including strip mining as shown here at this uranium mine. If there is a large enough amount present, the rock will be extracted and processed in a variety of ways (depending on the type of mineral) to remove the mineral from the surrounding rock. Once they are extracted and processed, the minerals can be turned into whatever products are desired, including the components in your cell phones and computers. One of the best known metals, gold, is extracted from gold ore like this sample.

 

Extraction

The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth’s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called gangue. The extraction of metals and its isolation occurs over few major steps:
• Concentration of Ore
• Isolation of metal from the concentrated Ore
• Purification of the metal

Difference between Minerals and Ores

 

Minerals	Ores
All the naturally occurring substances of metals which are present in the earth’s crust are known as Minerals.	Ores are usually used to extract metals economically. A large amount of metals are present.
All Minerals are not ores.	All ores are minerals.
Minerals are native form in which metals exist.	Ores are mineral deposits.

Ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted. Ores are found in rocks and minerals, and they are often mined using open-pit or underground mining methods.

There are many different types of ores, and each type contains a different metal or mineral. Some common types of ores include:

• Agate: Agate is a type of chalcedony, which is a form of quartz. Agate is often used in jewelry and other decorative items.
• Bauxite: Bauxite is the ore of aluminum. It is a soft, white or reddish-brown rock that is found in tropical and subtropical regions.
• Chromite: Chromite is the ore of chromium. It is a black ore that is found in igneous and Metamorphic Rocks.
• Cobalt: Cobalt is a metal that is used in alloys, batteries, and magnets. It is found in the ores of nickel, copper, and silver.
• Copper: Copper is a metal that is used in electrical wiring, plumbing, and coins. It is found in the ores of chalcopyrite, bornite, and malachite.
• Diamond: Diamond is a mineral that is composed of carbon. It is the hardest natural substance on Earth, and it is used in jewelry and industrial applications.
• Fluorspar: Fluorspar is a mineral that is composed of calcium fluoride. It is used in the production of aluminum, steel, and glass.
• Gold: Gold is a metal that is used in jewelry, coins, and electronics. It is found in the ores of gold telluride, pyrite, and arsenopyrite.
• Iron ore: Iron ore is the ore of iron. It is a rock that contains iron oxide, and it is used in the production of steel.
• Lead: Lead is a metal that is used in batteries, ammunition, and solder. It is found in the ores of galena, cerussite, and anglesite.
• Manganese: Manganese is a metal that is used in steel production, batteries, and Fertilizers. It is found in the ores of rhodochrosite, manganite, and pyrolusite.
• Mercury: Mercury is a metal that is used in thermometers, barometers, and dental fillings. It is found in the ore of cinnabar.
