Azurite or Azure spar [5]: 14 is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite , after the type locality at Chessy-les-Mines near Lyon , France . [ 3 ]
The principal mines were the Iron Mountain Mine, Mammoth Mine, and the Balaklala Mine. Copper production began in 1894, and continued off-and-on until 1976. Total production was 320 thousand tonnes of copper , 93 million pounds of zinc , 36 million troy ounces of silver , and 520,000 ounces of gold .

Azurite & malachite almost invariably occur together, and are telling indicators of copper in the field, even in very small quantities. Blue azurite tends to crystallize first, and can convert to green malachite. Some azurite-malachite specimens are solid enough to be cut and polished as semi-precious stone.
Associated minerals include: rosasite, smithsonite, hemimorphite, hydrozincite, malachite and azurite. [ 2 ] It was first described in 1839 by Bottger who named the mineral for its zinc and copper content after the Greek όρειχαλκος , for "mountain brass" or "mountain copper", the name of orichalcum , a fabulous metal, mentioned in the ...
