The Chelopech mine is one of the largest gold mines in Bulgaria. [1] The mine is located at the western part of the country in Sofia Province. [1] The mine has estimated reserves of 41 tons of gold and 4,182 tons of silver. [1]
Mining is the extraction of valuable geological materials from the Earth and other astronomical objects. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.

The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.75 miles (1,210 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres. It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013.
Chelopech is a village in the western part of Bulgaria. It is the only village in the Chelopech Municipality, Sofia Province.
Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 percent to the country's GDP. Add other mining-related industries and this figure increases to just four percent (2005). Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, exploration difficulties, and government control.
Mining in Brazil is centered on the extraction of iron, copper, gold, aluminum, manganese, tin, niobium, and nickel. About gemstones, Brazil is the world's largest producer of amethyst, topaz, agate and is a big producer of tourmaline, emerald, aquamarine, garnet and opal.
Romania ranks tenth in the world in terms of the diversity of minerals produced in the country. Around 60 different minerals are currently produced in Romania. The richest mineral deposits in the country are halite.
Gold mining in the People's Republic of China has made that country the world's largest gold producer. In 2022, China mined 403 tons of gold. Data indicates the marginal costs are often above the world price for gold. For the year 2007, gold output rose 12% from 2006 to 276 tonnes to become the world's largest for the first time—overtaking South Africa, which produced 272 tonnes. South Africa had until then been the largest for 101 years straight since 1905. The major reasons for this change in position had been due to South African production falling by 50% in the past decade as production costs there have risen, more stringent safety regulations have been implemented, and existing mines have become depleted.
Mining is important to the economy of Ethiopia as a diversification from agriculture. Currently, mining comprises only 1% of GDP. Gold, gemstones, and industrial minerals are important commodities for the country's export-oriented growth strategy.
Karlievo is a village in western Bulgaria. It is located in the municipality of Zlatitsa, in Sofia Province. As of 2007 the village had 245 inhabitants.
There are different methods by which gold mining companies are ranked. One is by their annual production. Another is by their cash cost per ounce, that is, how much money it costs them to mine the gold. Since gold prices are the same everywhere, companies with lower costs per ounce make more profit. The most common method lists by market capitalization which considers the total value of capital holdings by that company. Also considered when comparing companies is their market capitalization per ounce of gold equivalent which takes the market value and total reserves and resources for each company as well as the price of gold into consideration. The figures for each company can be used to determine the value the stock market gives to each company's reserves on an ounce to ounce basis.
Mount Morgan Mine was a copper, gold and silver mine in Queensland, Australia. Mining began at Mount Morgan in 1882 and continued until 1981. Over its lifespan, the mine yielded approximately 262 metric tons of gold, 37 metric tons of silver and 387,000 metric tons of copper. The mine was once the largest gold mine in the world.
Roșia Montană Project is a proposed gold and silver mine in Roșia Montană, Romania. If approved, it would become Europe's largest open-pit gold mine and it would use the gold cyanidation mining technique. The project met with widespread protests in 2013 that indefinitely delayed the project.
Kostovite is a rare orthorhombic-pyramidal gray white telluride mineral containing copper and gold with chemical formula AuCuTe4.
Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such as magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes, particularly in the North and South Hamgyong Province and Chagang Province. However, often these cannot be mined due to the acute shortage of electricity in the country, as well as the lack of proper tools to mine these materials and an antiquated industrial base. Coal, iron ore, limestone, and magnesite deposits are larger than other mineral commodities. Mining joint ventures with other countries include China, Canada, Egypt, and South Korea.
The mining industry of Togo is centred mainly around the extraction of phosphate, ranking it 19th in world production. Other minerals extracted are diamond, gold, and limestone. More minerals identified but yet to be brought into production mode are manganese, bauxite, gypsum, iron ore, marble, rutile, and zinc. The mineral sector contributes 2.8% to the country's gross domestic product (GDP).
The mining industry of Yemen is at present dominated by fossil mineral of petroleum and liquefied natural gas (LNG), and to a limited extent by extraction of dimension stone, gypsum, and refined petroleum. Reserves of metals like cobalt, copper, gold, iron ore, nickel, niobium, platinum-group metals, silver, tantalum, and zinc are awaiting exploration. Industrial minerals with identified reserves include black sands with ilmenite, monazite, rutile, and zirconium, celestine, clays, dimension stone, dolomite, feldspar, fluorite, gypsum, limestone, magnesite, perlite, pure limestone, quartz, salt, sandstone, scoria, talc, and zeolites; some of these are under exploitation.
