Mining history of Cyprus Copper mines Euromines

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.

COPPER Copper production TU Delft

Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.
