Exempel på hur man kan använda CHALCOCITE i en mening

• However, most chalcocite occurs in the supergene enriched environment below the oxidation zone of copper deposits as a result of the leaching of copper from the oxidized minerals.
• Minerals include chalcocite, bornite and chalcopyrite, with associated malachite, azurite and cuprite.
• Commonly found as coatings on chalcocite, chalcopyrite, bornite, enargite, pyrite, and other sulfides, it often occurs as pseudomorphic replacements of other minerals.
• It is a medium to low temperature hydrothermal mineral occurring with quartz, pyrite, sphalerite, galena, bornite, tetrahedrite–tennantite, chalcocite, covellite and baryte.
• It is typically associated with and often intergrown with chalcocite, covellite, djurleite, bornite, chalcopyrite and pyrite.
• It occurs with other supergene minerals such as chalcocite, covellite and digenite in the enriched zone of copper orebodies.
• Metallic minerals identified at Pebble include pyrite, chalcopyrite, molybdenite, and bornite, along with minor covellite, chalcocite, digenite and magnetite.
• Another district contains chalcopyrite, chalcocite, and bornite, in a fault zone that runs 25 miles in slate from Sykesville to Finksburg in Carroll County.
• The ore consisted of the uranium-vanadium minerals tyuyamunite, metatyuyamunite, and carnotite, along with the copper minerals covellite, chalcocite, azurite, and malachite, and the copper-vanadium mineral volborthite, in the Maroon Formation of Pennsylvanian-Permian age.
• Although native copper was the dominant ore mineral, chalcocite (copper sulfide) was sometimes present, and, especially in the Mohawk mine, copper arsenide minerals such as mohawkite and domeykite.
• Other copper minerals, such as the oxide cuprite and the sulfide chalcocite may require addition of oxidizing agents such as ferric sulfate and oxygen to the leachate before the minerals are dissolved.
• The ore deposits are classified as supergene oxide copper deposits and are primarily composed of weathered copper sulphide primary ores now present as a variety of copper carbonate minerals and secondary sulphides - primarily chalcocite - hosted within slate and conglomerate.
• These altered zones include chalcopyrite, pyrite, bornite and molybdenite as hypogene minerals and chalcocite as a supergene mineral.
• It occurs in association with chalcocite, bornite, willemite, smithsonite, hydrozincite, hemimorphite, adamite, olivenite and gebhardite.
• The operation of mining was divided into mining the hypogene sulfide mineralization (chalcopyrite) at depth and the shallow supergene (chalcocite) and oxidized deposit (chrysocolla, malachite, native copper and cuprite).
• When viewed under a microscope in plane polarized light, skaergaardite appears to be bright creamy white (in the presence of bornite or chalcopyrite) or bright white (in the presence of digenite or chalcocite).
• Although the primary mineral was copper, there are other minerals that can be found in the mine tailings such as brochantite, cassiterite, chalcocite, chalcopyrite, chamosite, connellite, langite, pyrite, quartz, copper(I) oxide (known locally as tile ore) and orthochamosite (daphnite).
• Associated minerals include arsenopyrite, stannoidite, chalcopyrite, chalcocite, sphalerite and tennantite.
• Associated minerals include chalcocite, atacamite, native copper, diopside, grossular, and vesuvianite.
• A barren, leached cap, in places up to 300 metres thick, overlies a thick zone of high grade secondary supergene mineralisation of the main orebody, largely chalcocite and covellite, which in turn overlies the unaltered primary mineralisation of chalcopyrite, bornite and pyrite.
