Timeline Of Mining In Colorado
Colorado mining history is a chronology of precious metal mining (e.g., Gold mining in Colorado, mining for gold and Silver mining in Colorado, silver), fuel extraction (e.g., Uranium mining in Colorado, mining for uranium and Coal mining in Colorado, coal), building material quarrying (iron, gypsum, marble), and rare earth mining (titanium, tellurium). The Uravan Mineral Belt (UMB) is on the west side of the state, and the Colorado Mineral Belt (COMB) is a large area of the state had gold/silver booms. Outside of the UMB & COMB, the Denver Basin produced small amounts of gold, and the Cripple Creek district had a different gold boom.

Climax Mine
The Climax mine, located in Climax, Colorado, United States, is a major molybdenum mine in Lake and Summit counties, Colorado. Shipments from the mine began in 1915. At its highest output, the Climax mine was the largest molybdenum mine in the world, and for many years it supplied three-fourths of the world's supply of molybdenum. After a long shutdown, the Climax mine has reopened and resumed shipment of molybdenum on May 10, 2012. The mine is owned by Climax Molybdenum Company, a subsidiary of Freeport-McMoRan. History The prospector Charles Senter discovered and claimed the outcropping of molybdenite (molybdenum sulfide) veins in 1879, during the Leadville, Colorado Silver Boom, but had no idea what the mineral there was. Senter determined that the rock contained no gold or silver, but retained the claims. The following year he settled with his Ute wife a few miles north, and he made a living working a nearby gold placer. Each year he performed the assessment work required to ...

Titanium
Titanium is a chemical element with the Symbol (chemistry), symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Kingdom of Great Britain, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titan (mythology), Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll process, Kroll and Hunter process, Hunter processes. The most common compound, titanium dioxide, is a popular photocatalysis, photocatalyst and is used in the manufacture of white pigments ...

Gunnison River
The Gunnison River is located in western Colorado, United States and is one of the largest tributaries of the Colorado River. Description The river flows east to west and has a drainage area of according to the USGS. The drainage basin of the Gunnison collects water from different habitats, such as forests and alpine meadows, located the along Continental Divide. As the river flows westward, it carves through the San Juan Mountains. It flows into the Colorado River at Grand Junction. The Gunnison River Basin is popular for recreational activities such as fishing, rafting, boating, camping, hiking, and rock climbing. Contamination of the Gunnison River with selenium and mercury results from irrigation of high-selenium soils derived from the Mancos Shale and from mineral mining. The region surrounding the Gunnison River is part of the Colorado Mineral Belt. Contamination of the Gunnison River with selenium and mercury is a conservation concern for the bonytail chub, C ...

United States Atomic Energy Commission
The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb. An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the ...

Climax Uranium Mill
Climax Uranium Mill is a decommissioned uranium mill near Grand Junction, CO. The mill, which processed vanadium as well as uranium, was incorporated May 11, 1950. It was constructed on city-owned property next to the Colorado River which was once the Grand Junction sugar beet mill. Climax Uranium Company gutted the former sugar beet mill, removing any remaining equipment and stabilizing weak walls, and began uranium and vanadium milling operations. The mill soon grew to be 12 buildings large and processed 2 million tons of ore, mostly for the United States Atomic Energy Commission. The mill caused contamination in an aquifer directly beneath the surface of the site. Mill tailings were allowed to be taken for civilian and construction use in the city which led to many vicinity properties with elevated radiation levels. In 1970, the mill was decommissioned and most of the contaminated materials were brought to the Grand Junction Disposal Site. Some of the leftover tailings used in c ...

Cease And Desist
A cease and desist letter is a document sent to an individual or business to stop alleged illegal activity. The phrase "cease and desist" is a legal doublet, made up of two near-synonyms. The letter may warn that, if the recipient does not discontinue specified conduct, or take certain actions, by deadlines set in the letter, that party, i.e. the letter's recipient, may be sued. When issued by a public authority, a cease and desist letter, being "a warning of impending judicial enforcement", is most appropriately called a "cease and desist order". Usage for intellectual property Although cease and desist letters are not exclusively used in the area of intellectual property, particularly in regards to copyright infringement, such letters "are frequently utilized in disputes concerning intellectual property and represent an important feature of the intellectual property law landscape". The holder of an intellectual property right such as a copyrighted work, a trademark, or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
