Kupros: Copper in the history of Cyprus ...
Copper has been critical in the history of Cyprus - the Greek name for the ore - kupros - comes from the word Cyprus. A Cyprus Museum display (now disappeared) estimates that 200,000 tonnes of copper ingots were extracted by ancient workings from the Troodos ore deposits.

The enriched copper ores (copper concentrates) had an average content of about 19% and were exported from Cyprus. Because certain copper minerals (malachite, azurite, chrysocolla and partly chalcosite and cuprite) are dissolved in water (leaching), the dissolved copper was cemented with scrap iron producing copper cement with a content of about ...

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.

Mining industry of Cyprus - Wikipedia
Geologically the ore genesis model shows Cyprus’ copper deposits were created by volcanic activity. A better understanding of how the ore was formed has allowed Hellenic Copper Mines Ltd. to utilize extraction methods which result in higher yields. Their copper exports from the Skouriotissa mine were valued at US$13.1 million during 2010.

Three assemblages of ores have been recognized at the Proterozoic porphyry copper deposit, Malanjkhand, India. They are: (1) primary ore containing chalcopyrite and pyrite; (2) moderately oxidized ore containing chalcocite, covellite, bornite, and other secondary copper sulfides; and (3) intensely oxidized ore containing copper sulphates, carbonates, chlorides, oxides and native copper.

Innovations: Introduction to Copper: Mining Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...

Copper Mining and Production Processes Explained
Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
