Azurite from Burra Mine, South Australia. Azurite is found in the same geologic settings as its sister mineral, malachite, though it is usually less abundant. Both minerals occur widely as supergene copper minerals, formed in the oxidized zone of copper ore deposits. Here they are associated with cuprite, native copper, and various iron oxide ...
Azurite is a naturally occurring mineral found particularly in copper-mining areas of the world. [4] It is often found with malachite, a green basic carbonate of copper. There is evidence that azurite has been used since the dawn of modern civilization, dating back to the Fourth Dynasty in Egypt. [1]

It is alternatively called azuromalachite, azurite-malachite and malachite-azurite. [2] Azurmalachite has a distinctive mottled green and blue coloration. It is relatively rare but can sometimes be found above copper deposits. The main sources for mined azurmalachite are the United States, France, and Namibia. [3]

This specimen was in the personal collection of Dr. James Douglas, and was later donated to the Smithsonian by his son. [1] The Copper Queen Mine was a copper mine in Cochise County, Arizona, United States.
Mining occurs solely in one mid-sized open pit named the Centennial pit, and the primary ores are malachite, azurite, and chalcocite. The mine employs approximately 140 people as of February 2012. The mine employs approximately 140 people as of February 2012.
Copper has been mined on and off at Whim Creek over a period of 120 years. Copper was mined initially via a series of small adits and stopes into the Whim Creek and Mons Cupri deposits by artisanal miners, [1] with records indicating that as early as 1882 small quantities of malachite, azurite, chrysocolla and
This is a list of mining areas in Colombia. [1] The mineral industry of Colombia is large and diverse; the country occupies the first place in mining areas per surface area in the world. In pre-Columbian times, mining of gold, silver, copper, emeralds, salt, coal and other minerals was already widespread.
