Ore and gangue mineralogy and zonation The dominant sulfide mineral in most VMS deposits is pyrite, but pyrrhotite is dominant in others. Marcasite, which is present either intergrown with fine grained pyrite or as a replacement product of pyrrhotite, is generally a minor
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.

Typical Cyprus-type deposits comprise massive brecciated pyrite ores, underlain by a vertically extensive quartz-pyrite-chlorite stockwork. Sandy pyrite or conglomeratic ore, similar to that found in the TAG mound, is characteristic of the upper parts of Cyprus-type deposits.
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.

Apr 22, 2019· Elemental Sulfur raw material segment dominates the entire sulfuric acid market and projected to lead the market during the forecast period. Due to the abundant availability in the market and less polluting as compared to other raw material like pyrite ore or base metal smelters.
The metallurgical methods which were applied were mainly those of flotation of copper minerals (chalcopyrite, bornite, covellite, chalcosite and cuprite), iron pyrite and other sulfide minerals (sphalerite), if contained in the ore. The enriched copper ores (copper concentrates) had an average content of about 19% and were exported from Cyprus.
Ore mineral abundance is pyrite, chalcopyrite, sphalerite and magnetite in decreasing order. Gangue minerals are quartz, chlorite, sericite and carbonate . Pyrite is the most common mineral and displays euhedral and subhedral grains of a few microns to 5–6 cm. Pyrite is generally surrounded by chalcopyrite and gangue minerals.
