copper is the metal from Cyprus. Eventually the term Cyprium was used alone and even later it was changed to cuprum. It is from this Latin word that the name for the metal in most western European languages is derived. The most important evidence for the extent for the copper mining activity in antiquity is the number of slag heaps found ...

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

The word 'copper' comes from the Latin Cyprium aes, the term used by the Romans for copper from Cyprus. These were made from native copper that would not have required mining. The first smelted copper dates from 2500 BC and was made using arsenic rather than tin as an alloy. Tin alloyed copper (ie bronze) was not made until 1900 BC and did …

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
