Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. 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 Berkeley Pit is a former open pit copper mine in the western United States, located in Butte, Montana. It is one mile (1.6 km) long by one-half mile (800 m) wide, with an approximate depth of 1,780 feet (540 m). It is filled to a depth of about 900 feet (270 m) with water that is heavily acidic, about the acidity of Coca-Cola, lemon juice, or gastric acid. As a result, the pit is laden with heavy metals and dangerous chemicals that leach from the rock, including copper, arsenic, cadmium, zinc, and sulfuric acid.
The Argyle Diamond Mine was a diamond mine located in the East Kimberley region in the remote north of Western Australia. Argyle was at times the largest diamond producer in the world by volume, although the proportion of gem-quality diamonds was low. It was the only known significant source of pink and red diamonds, and additionally provided a large proportion of other naturally coloured diamonds, including champagne, cognac and rare blue diamonds.

Codelco is a Chilean state-owned copper mining company. It was formed in 1976 from foreign-owned copper companies that were nationalised in 1971.
Silver mining is the extraction of silver from minerals, starting with mining. Silver itself is a precious metal and holds high economic value as it is regarded as a rare metal. Because silver is often found in intimate combination with other metals, its extraction requires elaborate technologies. In 2008, ca. 25,900 metric tons were consumed worldwide, most of which came from mining. Silver mining has a variety of effects on the environment, humans, and animals.
Mining in Western Australia, together with the petroleum industry in the state, accounted for 94% of the State's and 46% of Australia's income from total merchandise exports in 2019–20. The state of Western Australia hosted 123 predominantly higher value and export-oriented mining projects and hundreds of smaller quarries and mines. The principal projects produced more than 99 per cent of the industry's total sales value.
Mount Isa Mines Limited ("MIM") operates the Mount Isa copper, lead, zinc and silver mines near Mount Isa, Queensland, Australia as part of the Glencore group of companies.

Iron ore mining in Western Australia, in the 2018–19 financial year, accounted for 54 percent of the total value of the state's resource production, with a value of A$78.2 billion. The overall value of the minerals and petroleum industry in Western Australia was A$145 billion in 2018–19, a 26 percent increase on the previous financial year.
Fatality statistics in the Western Australian mining industry captures the number of people killed in the industry in the Australian state of Western Australia. During the period 2000-2012 (inclusive), a total of 52 fatalities occurred. In 2006, the Chamber of Minerals and Energy of Western Australia commissioned a taxonomic study to analyse the 306 mining fatalities which occurred between 1970 and 2006. The Department of Mines and Petroleum, later renamed the Department of Mines, Industry Regulation and Safety, the governing authority for the industry in the state, has published statistics for fatalities in mining dating back to 1943 and intends to publish statistics dating back to 1886, though early records are not expected to be exhaustive.
The Kamoto Mine is an underground copper and cobalt mine to the west of Musonoi in the former Katanga Province, Democratic Republic of the Congo. As of 2022, the site is the largest active cobalt mine in the world. The mine includes the Luilu metallurgical plant, which accepts ore from KOV mine and Mashamba East mine. The plant has polluted the Luilu River, and tailings also pollute the region with wind-blown dust. The Kolwezi Tailings Project is an attempt to recover additional metal from these tailings.
Mopani Copper Mines PLC is a Zambian company that produces and sells copper and cobalt to the international market, being one of the biggest mines and exporters in the world.
The Carrapateena mine is a large copper mine under development in South Australia's Far North region 100 km southeast of Olympic Dam and approximately 160km north of Port Augusta. Carrapateena represents one of the largest copper reserves in Australia and in the world having estimated reserves of 292 million tonnes of ore grading 1.31% copper and 3.64 million oz of gold. It was discovered by explorer and metallurgist Rudie Gomez in 2005. The project was acquired by OZ Minerals in 2011, and the project was referred to the EPBC Act for Federal environmental approval in 2012. Construction of the decline to access the mine commenced in 2016. The mining technique used to extract the ore is sub-level caving.
