The main minerals in this deposit are sulphide minerals such as pyrite, sphalerite, chalcopyrite and galena. The term “massive sulfide” deposit refers to any deposit containing more than 50% sulfide minerals. The modifier “volcanogenic” indicates that the massive sulfides are believed to be genetically related to volcanism that was ...Sphalerite is an important host mineral for a wide range of minor and trace elements. We have used laser-ablation inductively coupled mass spectroscopy (LA-ICPMS) techniques to investigate the distribution of Ag, As, Bi, Cd, Co, Cu, Fe, Ga, Ge, In, Mn, Mo, Ni, Pb, Sb, Se, Sn and Tl in samples from 26 ore deposits, including specimens with wt.% levels of …The highest In content in sphalerite is characteristic of chalcopyrite-free ore-bearing mineral assemblages. The sphalerite-chalcopyrite association is, however, typical of the proper indium mineral, roquesite. Sphalerite in this association is distinguished by a low indium content (260–657 ppm).

Sulfides are well known for being important ore minerals. For example, galena is the main source of lead, sphalerite is the main source of zinc, and chalcopyrite is the main copper ore mineral mined in porphyry deposits like the Bingham mine (see chapter 16). The largest sources of nickel, antimony, molybdenum, arsenic, and mercury are also ...

Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often ...

Chalcopyrite was the mineral upon which Bronze Age civilizations were built. Within the last century, it also became the mineral foundation for our modern electrical age. Our primary source of copper, chalcopyrite’s name comes from the Greek words ‘chalkos’ and ‘pyrites’, which respectively mean ‘copper’ and ‘striking fire’.

The mineral marcasite, sometimes called "white iron pyrite", is iron sulfide (FeS 2) with orthorhombic crystal structure.It is physically and crystallographically distinct from pyrite, which is iron sulfide with cubic crystal structure.Both structures contain the disulfide S 2 2− ion, having a short bonding distance between the sulfur atoms.

This mineral specimen is from the Eagle mine, Gilman mining district, Eagle County, Colorado. Raines, Ed.In Our Society: The Economic Importance of Pyrite. Despite being a common, iron-rich mineral, pyrite is rarely mined for its own sake, and most of our iron is produced from magnetite and hematite deposits. Those iron oxide minerals occur in larger concentrations and volumes than pyrite, so they are a more economical iron source.

Sphalerite, the most economically significant zinc ore mineral, commonly contains minor amounts of cadmium, which shares certain similar chemical properties with zinc and often substitutes for zinc in the sphalerite crystal lattice. The cadmium mineral greenockite is frequently associated with weathered sphalerite and wurtzite.Also massive, granular to compact. Bournonite is a sulfosalt mineral species, trithioantimoniate of lead and copper with the formula PbCuSbS 3.
