In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Pebble Mine is the common name of a proposed copper-gold-molybdenum mining project in the Bristol Bay region of Southwest Alaska, near Lake Iliamna and Lake Clark. It was discovered in 1987, optioned by Northern Dynasty Minerals in 2001, explored in 2002, and drilled from 2002-2013 with discovery in 2005. Preparing for the permitting process began and administrative review lasted over 13 years.
Uranium mining in the United States produced 173,875 pounds (78.9 tonnes) of U3O8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds (656.8 tonnes) of U3O8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year.
In the United States, gold mining has taken place continually since the discovery of gold at the Reed farm in North Carolina in 1799. The first documented occurrence of gold was in Virginia in 1782. Some minor gold production took place in North Carolina as early as 1793, but created no excitement. The discovery on the Reed farm in 1799 which was identified as gold in 1802 and subsequently mined marked the first commercial production.
Iluka Resources is an Australian-based resources company, specialising in mineral sands exploration, project development, operations and marketing. Iluka is the largest producer of zircon and titanium dioxide–derived rutile and synthetic rutile globally. Iluka mines heavy mineral sands and separates the concentrate into its individual mineral constituents rutile, ilmenite, and zircon. Some of the ilmenite is then processed into synthetic rutile.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium mining started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s. Since 2001 there has been a revival of interest in uranium mining, as a result of higher uranium prices.
Uranium mining in Arizona has taken place since 1918. Prior to the uranium boom of the late 1940s, uranium in Arizona was a byproduct of vanadium mining of the mineral carnotite.
Madawaska Mine (previously known as Faraday Mine) is a decommissioned underground uranium mine in Faraday, near the town of Bancroft, Ontario, which produced 9 million pounds (4,082 tonnes) of U3O8 concentrate, at an average ore grade of 0.1074%, during its two periods of production.
Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the United States, no uranium ore has been mined in New Mexico since 1998.
The mineral industry of Mozambique plays a significant role in the world's production of aluminium, beryllium, and tantalum. In 2006, Mozambique's share of the world's tantalum mine output amounted to 6%; beryllium, 5%; and aluminium, 2%. Other domestically significant mineral processing operations included cement and natural gas.
The Portland railway line is a railway line in south-western Victoria, Australia. It runs from the main Western standard gauge line at Maroona through Hamilton to the port town of Portland.
Uranium mining and the Navajo people began in 1944 in northeastern Arizona, northwestern New Mexico, and southeastern Utah.
