chalcopyrite

(ˌkælkəˈpaɪraɪt; -ˈpaɪə-)
n
(Minerals) a widely distributed yellow mineral consisting of a sulphide of copper and iron in tetragonal crystalline form: the principal ore of copper. Formula: CuFeS2. Also called: copper pyrites

chal•co•py•rite

(ˌkæl kəˈpaɪ raɪt)

n.
a common mineral, copper iron sulfide, CuFeS2, occurring in brass-yellow crystals or masses: the most important ore of copper; copper pyrites.

chal·co·py·rite

(kăl′kə-pī′rīt′)
A yellow metallic mineral consisting of iron, copper, and sulfur. Chalcopyrite usually occurs as shapeless masses of grains and is an important ore of copper. Because of its shiny look and often yellow color, it is sometimes mistaken for gold, and for this reason it is also called fool's gold.

Further drilling approximately 2.3 kilometers to the northeast along the Burgundy - Telena - 72' Zone trend intercepted new mineralization hosted in potassic/hematite altered intrusions in the form of disseminated, and vein-hosted chalcopyrite + bornite adjacent to historic high-grade Cu-Au-Ag skarn-type mineralization.
Preliminary mapping of the trench exposures shows that the massive sulphides (chalcopyrite dominant) are hosted within structurally controlled fault-breccias that occur within a sequence of metasedimentary rocks and a white, medium-grained monzonite granite.
Mineralisation consists of native gold associated with pyrite, chalcopyrite and sphalerite disseminated in quartz veins within a linear body of diorite within volcanic rocks.
The identification of chalcopyrite and sphalerite associated with the massive sulphide mineralization, and with host lithology similar to that at the Prieska deposit, suggests the discovery of a volcanogenic massive sulphide (VMS) deposit.
The ore minerals observed include, pyrite, chalcopyrite, magnetite, molybdenite, galena etc.
Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is obtained by using traditional methods such as underground mining and open-pit mining, with the latter method accounting for 90% of the ore used in smelting.
The surface mineralisation at BEP and BWP comprises chalcocite, covellite and digenite mineralisation with lesser chalcopyrite. The outcropping BSK deposit comprises a garnet--magnetite skarn with chalcocite-malachite-azurite in the upper section and chalcopyrite-bornite mineralisation at depth.
studied the influence of metal ions (such as [Ca.sup.2+], [Mg.sup.2+], [Fe.sup.2+], [Fe.sup.3+], [Cu.sup.2+], [Zn.sup.2+], and [Al.sup.3+]) in the pulp on the chalcopyrite and galena floatability [15].
The chalcopyrite family of compounds I-III-[VI.sub.2] (I = Cu, Ag, III = Al, Ga, In, VI = S, Se, Te) form a wide group of chalcogenide semiconductor materials with diverse optical and electrical properties [1].
In the Fuzishan Cu-Mo deposit, the metallic minerals include pyrite, chalcopyrite, bornite, chalcocite, molybdenite, sphalerite, magnetite, and hematite.
