The oldest known flint mine was in Nazlet Sabah (Egypt)
Man does not find many necessary materials on the surface of the Earth. Therefore, people began to drill and dig the ground since ancient times to find the necessary raw materials. The earth is a treasure trove of mineral wealth. However, as a result of centuries of extensive exploitation, many ores and natural raw materials are becoming rarer and more expensive day by day. Man always needs to dig the earth, drill and extract rocks to find materials. This affects the appearance and landscape of planet Earth. The oldest known mine was in Nazlet Sabah (Egypt). Flint was mined there several thousand years ago. Today, more than 15 million miners work in mines in the world (if quarry workers are added, the number is over 300 million). Today, over 50 billion tons of rocks and soil are mined in the world to find the desired material (ore). A hole is made that is only one meter deep but has an area larger than Switzerland.
- Copper – the largest open-air copper mine is Chuikuikamata (Chile). The deepest copper mine is in Carletonville (South African Republic). It has a depth of up to 3,581 meters. Excavated soil is cleaned with a sieve. Layer by layer is then deposited using an excavator. The result is a strange and fan-shaped appetizer.
- Oil – in 2002, more than 3.33 billion tons of oil were extracted in the world. The global network of oil pipelines is over 580.00 km long. It could circle the planet Earth 14 times. Oil has created a black river in the Tunisian desert due to a pipeline failure.
- Lignite – the former lignite mine is given a strange appearance by the green bags placed to prevent the penetration of unpleasant odors. From 1930 to 1990, this mine was a waste dump for the nearby cellulose fiber factory in Johannes (Germany).
- Lignite-lignite is found at shallower depths in the German Hoiersdorf mine. That is why the greater part of the mine is under the open sky.
- Uranium – residues from processing during the extraction of uranium in the Arlit mine (Niger) made an unusual appearance. This deposit was found in 1965. Every year, 3,000 tons of uranium are extracted, or 8 tons of the world’s total annual production of uranium. It is used mainly to start nuclear power plants.
- Marble and granite – more than 10.1 million tons of marble and granite are extracted every year in Italy alone. This accounts for about 13% of world production. The most famous marble deposits are in the Apuan Alps (near Tuscany). This is where the ancient Romans dug and extracted the famous white marble. Michelangelo made his most famous works from white marble.
- Gold – waste from gold mines on the island of Mindanao (Philippines) created the appearance that is achieved after a storm. It is necessary to dig and extract 12 tons of soil and minerals to obtain 28 grams of gold. Waste and harmful substances (used for processing gold) are poured into the sea. Thus, they cause incalculable and irreversible damage to the sea and nature.
- Uranium- Australia is the second producer of uranium in the world (Canada is the first producer of uranium in the world). In the mine in Kakadu Park, huge jets of water prevent the scattering of harmful particles.
