Morenci and Turquoise Peak are either inactive or depleted. The Kingman Mine as of 2015 still operates alongside a copper mine outside of the city. Some phosphate rock deposits, such as Mulberry in Florida,[11] are notable for their inclusion of significant quantities of radioactive uranium isotopes.

Nevada has produced a wide diversity of colours and mixes of different matrix patterns, with turquoise from Nevada coming in various shades of blue, blue-green, and green. [13][14] The pre-Columbian Aztec and Maya also considered it to be a valuable and culturally important stone.[15]. Nevada is the country's other major producer, with more than 120 mines which have yielded significant quantities of turquoise. Other natural materials occasionally confused with or used in lieu of turquoise include: variscite and faustite;[5] chrysocolla (especially when impregnating quartz); lazulite; smithsonite; hemimorphite; wardite; and a fossil bone or tooth called odontolite or "bone turquoise", coloured blue naturally by the mineral vivianite. It strikes at a bearing of about 15° and extends from the northern part of Elko County, southward down to the California border southwest of Tonopah.

Since finer turquoise is often found as thin seams, it may be glued to a base of stronger foreign material for reinforcement. Staining between grain boundaries may be visible in dyed imitations. [citation needed]. ), Material treated with plastic or water glass is termed "bonded" or "stabilized" turquoise. Turquoise prehistoric artifacts (beads) are known since the fifth millennium BCE from sites in the Eastern Rhodopes in Bulgaria – the source for the raw material is possibly related to the nearby Spahievo lead–zinc ore field.

copper 1 phosphate formula

Because of the geology of the Nevada deposits, a majority of the material produced is hard and dense, being of sufficient quality that no treatment or enhancement is required. In spite of increased costs, small scale mining operations continue at a number of turquoise properties in Nevada, including the Godber, Orvil Jack and Carico Lake mines in Lander County, the Pilot Mountain Mine in Mineral County, and several properties in the Royston and Candelaria areas of Esmerelda County. The various metaphosphate ions (which are usually long linear polymers) have an empirical formula of (PO3)− and are found in many compounds. Once used, it is often a limiting nutrient in environments, and its availability may govern the rate of growth of organisms. All Bisbee turquoise was "lunch pail" mined. Most of the pieces made today, with turquoise usually roughly polished into irregular cabochons set simply in silver, are meant for inexpensive export to Western markets and are probably not accurate representations of the original style. This region was known as the Country of Turquoise by the native Monitu. Only one mine in California, located at Apache Canyon, operates at a commercial capacity today.
