Mining

is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron

ore

. Iron ore is the material from which the metal iron is produced.

The process of Mining dates back to

prehistoric

times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges. The Mining of gold and copper also dates back to prehistoric times.

These profitable substances that are mined from the earth are called minerals. A

mineral

is typically an

inorganic

substance that has a specific chemical composition and

crystal

structure. The minerals are valuable in their pure form, but in the earth they are mixed with other, unwanted rocks and minerals. This mix of rock and minerals is usually carried away from the mine together, then later processed and refined to isolate the desired mineral.

The two major categories of modern Mining include surface Mining and underground Mining. In surface Mining, the ground is blasted so that ores near Earth’s surface can be removed and carried to refineries to

extract

the minerals. Surface Mining can be destructive to the surrounding landscape, leaving huge open pits behind. In underground Mining, ores are removed from deep within the earth. Miners blast tunnels into the rock to reach the ore deposits. This process can lead to accidents that trap miners underground.

Along with accidents, a career in Mining can also be dangerous since it can lead to health problems. Breathing in dust particles produced by Mining can lead to lung disease. One of the most common forms is black lung disease, which is caused when coal miners breathe in coal dust. Many other types of Mining produce silica dust, which causes a disease similar to black lung disease. These are incurable diseases that cause breathing impairment and can be fatal.

The Mining process can also harm the environment in other ways. Mining creates a type of water pollution known as

acid

mine drainage. First, Mining exposes sulfides in the soil. When the rainwater or streams dissolves the sulfides, they form acids. This acidic water damages aquatic plants and animals. Along with

acid mine drainage

, the disposal of mine waste can also cause severe water pollution from toxic metals. The toxic metals commonly found in mine waste, such as arsenic and mercury, are harmful to the health of people and wildlife if they are released into nearby streams.

What is mining in simple words?

Mining is the process of digging things out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction. Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, tin and iron.

What is mining and types of mining?

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.

What is the best definition of mining?

mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.

What is mining process?

Mining is the process used to extract valuable resources from the Earth. It is done to acquire any resource that cannot be grown or fabricated through artificial means. More specifically, mining is used to extract non-renewable resources like fossil fuels, minerals and even water.

What is mining in Wikipedia?

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.

What are in mines?

By Lisa Algee. Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined.

Why is it called mining?

Mining is a metaphor for introducing new bitcoins into the system because it requires (computational) work just as mining for gold or silver requires (physical) effort. Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain.

What is mining PDF?

Mining is the extraction of economically valuable minerals or other geological materials from the earth surface. It may be from an ore body, lode, vein, seam, reef or placer deposits.

How is mining important?

IMPORTANCE OF MINING Mined materials are needed to construct roads and hospitals, to build automobiles and houses, to make computers and satellites, to generate electricity, and to provide the many other goods and services that consumers enjoy.
