Abstract. Busang prospect occurs in the Kalimantan Volcanic belt of East Kutai Regency, East Kalimantan. The prospect occupied the undulated morphology known as Bukit Busang. It is approximately 150 km southwest of the Kelian mine. Geologically, the Busang prospect is hosted within the volcanic rocks (tuff, breccia, dacite and adesite).
Chalcopyrite, CuFeS2, is the most important copperbearing mineral in the world and unlike many other ores it is known to be recalcitrant to hydrometallurgical processing. The main hindrance to the commercial applica tion of biohydrometallurgical processing of chalcopyrite is its slow rate of dissolution.

Chalcopyrite mineral information and data Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits.
Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, MississippiValley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite ...
Au mineral exploration in the SW Pacific rim in the early 1990s facilitated initial development ... anhydrite, pyrite, chalcopyrite and bornite, within the innermost potassic alteration provide a geophysical signature of a magnetic, resistive and moderately chargeable body. ... Indonesia and Lihir, Papua New Guinea.
The concentrate is based on chalcopyrite. It contains subordinate pyrite and accessory sphalerite and stannite. Width of microphoto corresponds to 550 microns. 4. Copper concentrate (Ertsberg/Indonesia). Heterogeneous concentrate based on chalcopyrite and bornite with subordinate amounts of covellite and digenite.
· Cornish Connellite on Quartz with Chalcopyrite Mineral. Rare secondary copper mineral connellite, on this rare example of quartz with chalcopyrite from Parc An Oweth, Botallack, Cornwall, England, named after Professor Arthur Connell. approximate size: 44mm x 43mm x 27mm. *actual item.
A larger cabinet size specimen with an attractive grouping of three minerals. The dolomite preferentially covers one face of the red quartz. Chalcopyrite crystals are sprinkled across the display face. This specimen comes from Dongxiang Co., Jiangxi Province, Inner Mongolia, China.
Through its subsidiary, PTFI, FCX mines one of the world's largest copper and gold deposits in the Grasberg minerals district in Papua, Indonesia. In addition to copper and gold, PTFI produces silver. FCX has a percent interest in PTFI and manages its mining operations. PTFI's results are consolidated in FCX's financial statements.
· Mineral‐binding selectivity was demonstrated by binding studies, zeta potential determination and immunochemistry. Peptides that have the ability to discriminate between enargite and chalcopyrite provide a greener option for the separation of arsenic containing contaminants from copper concentrates.
Beutong is a large highquality copper, gold, silver, molybdenum deposit outcropping at surface and remaining open laterally and at depth. Contained metal in Resource on a basis comprises () copper, gold and silver ( () copper, gold and silver on an 80% attributable basis) The ...
Mineralogical analyses performed by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) and Xray diffraction of the bulk concentrate revealed that the sample contained mainly chalcopyrite with sphalerite, pyrite and small amounts of bornite. The primary gangue mineral was quartz.
Associated copper minerals include the sulfides bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu2O). Chalcopyrite is rarely found in association with native copper. Chalcopyrite is the most important copper ore.
Chalcocite has been known to form pseudomorphs of the minerals bornite, covellite, chalcopyrite, pyrite, enargite, millerite, galena and sphalerite. Pseudo means false and morph means shape or form, thus pseudomorph means false shape since the mineral is chalcocite but the shape is that of a covellite crystal, for example.
Within these veins, multiphases, colloformcrustiform, bedding to massive textures with pyrite, sphalerite, galena, chalcopyrite, chalcocite, azurite, and malachite are observed. Selected samples were analyzed by using ore microscopy and SEMEDX. Ore minerals show replacement, exsolution, colloform, and zonal textures.
Chalcopyrite. The most common copper mineral, a copper and iron sulfide, and a very important copper ore. It typically occurs in ore veins deposited at medium and high temperatures, as in Río Tinto, Spain; Ani, Japan; Butte, Mont.; and Joplin, Mo. Chalcopyrite (CuFeS 2) is a member of a group of sulfide minerals that crystallize in the tetragonal system; the group also includes .
Chalcopyrite crystals, with very well defined faces and edges, implanted on a druse of translucent Sphalerite crystals with a dark honey color, twinned and showing the dominant faces of a tetrahedron. An American classic. Commodore Mine, Creede District, Mineral County, Colorado USA Specimen size: × × cm = " × " × 1 ...
The chalcopyrite crystals are all sharp, brassy and bright, and measuer up to cm. There are numerous small tennantite crystals on the piece, the largest of which is 2 mm. The piece is in excellent condition absolutely no damage to anything central, a couple minor nicks to more peripheral crystals.
