The Mathiatis and Sha mines provide typical examples of abandoned mines where Cyprus-type Cu-pyrite ore was exploited. Supergene alteration of the sulphide ore and the mine waste leads to the formation of efflorescence and generation of acid mine drainage filling the pit-lakes.

The origin of the pyrite ore bodies was uncertain and controversial until the late 1970s when massive sulphides were discovered in association with high-temperature black smokers and vent biota at the crest of the East Pacific Rise, which confirms that the formation of new oceanic crust through seafloor spreading is intimately associated with ...
Chalcopyrite as a principal ore of copper is much more useful. Pyrite is paler yellow, chalcopyrite has more intense color. Width of sample 8 cm. Hannukainen, Finland. Large boulder of massive sulfide from Cyprus. It is called massive because it is indeed full of pyrite and contains little else. Here is an example of pyrite as a rock type.
The mining industry of Cyprus was active in the production of minerals of copper, iron pyrite, gold, chromites as well as asbestos fibers. Since 1979 the mining industry of Cyprus is in recession because of the exhaustion of the known large and rich copper and iron pyrite ore bodies and the increase of the production cost without proportional increase in the international sale prices of metals.
Constantinou and Govett (1973) define three different types of sulphide ore within Cyprus VHMS orebodies. Zones A, B and C are defined according to the style of pyrite mineralisation and amount of contained sulphur. Most ore bodies comprise Zone A mineralisation with either Zone B or Zone C making up the remainder of the ore-body.

The Xyliatos mines are located in the village of Xyliatos in the Nicosia district. The mines operated during the period 1954-1971 and partly during the period 1987-1990. The advantage was done on the surface with the method of the closed excavation and this brought around 2.125.000 tonnes of pyrite ore with an average content of 26% S.

The Mining industry of Cyprus is synonymous with copper extraction which began around 4,000 BC. Copper dominates the mining sector along with mining of iron pyrite, gold, chromites and asbestos fibers, bentonite, cement, and also petroleum.
Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m 3.
supergene sulfide mineral assemblages in ancient deposits are dominated by a small group of Cu-rich minerals: chal-cocite, bornite, covellite, digenite, and enargite. In the super-gene blanket, these sulfides may be intergrown with varying amounts of relict hypogene sulfides such as pyrite, chalco-pyrite…

The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname ...
Jun 01, 2012· Sulfide ore is called "massive" because it contains little else than pure pyrite.
