Included chalcopyrite adds a nice accent. The crystal is basically a floater, with only a slim rear-center attachment point showing. Quite a compelling and beautiful specimen - better in person where the human eye can discern more of the changes of clarity and color within Mined April of 1990. RCL 521

Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
Outstanding localities for Chalcopyrite include in the United States, Mexico, Peru, Canada, Slovakia, the Czech Republic, Germany, Norway, Japan, and South Africa. Chalcopyrite is commonly found in hydrothermal veins, stockworks, disseminations, massive replacements, mafic igneous exsolutions, and as a sedimentary mineral in reducing and ...
Chalcopyrite is commonly mined alongside these more precious metals and is in fact the single most important Copper ore. Enhancements All Chalcopyrite is natural, enhanced only by tumbling, cutting, and polishing. Map courtesy of TravelBlog Photos Rough Chalcopyrite. History of Chalcopyrite.
Mount Isa Mines operates two separate mining and processing streams, copper and zinc-lead-silver, near Mount Isa, Queensland, Australia. Its copper operations include two underground copper mines, Enterprise and X41, with ore mining capacity of 6.2 million tonnes per annum Mtpa, a concentrator with 7Mtpa capacity, a copper smelter, and support services.
Native or elemental copper can be found in nature, but most copper is mined as oxide or sulfide minerals. Chalcopyrite CuFeS2 is one copper mineral that can be converted to elemental copper in a series of chemical steps. Reacting chalcopyrite with oxygen at high temperature produces a mixture of copper sulfide and iron oxide. The iron oxide is seperated from CuS by reaction with sand SiO2.
Concentration data are reported for 18 trace elements in chalcopyrite from a suite of 53 samples from 15 different ore deposits obtained by laser-ablation inductively-coupled plasma-mass spectrometry.
Chalcopyrite in Australia is found in rocks that are more than 250 million years old. Bornite Cu 5 FeS 4 , covellite CuS and chalcocite Cu 2 S are important sources of copper in the world and many ore bodies also contain some malachite CuCO 3 .CuOH 2 , azurite Cu 3 CO 3 2.CuOH 2 , cuprite Cu 2 O, tenorite CuO and native copper.
