copper ore sulfer

The Extraction of Copper

Sulfide ores such as chalcopyrite ((CuFeS_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 ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation).

Copper in the Roman Empire

To smelt sulfide minerals, (that is minerals made of copper, iron, lead and zinc chemically bound to sulfur), it has to be heated and oxidized first. The more easily smelted ores were exhausted by the time of the fall of Rome. The Moors lived in southern Spain during the Middle Ages. They used copper for cooking utensils and for ornaments.

Applications: Copper Compounds

By heating copper scrap with sulphur to produce copper sulphide which is then oxidised to form copper sulphate. By heating copper sulphide ores to produce copper oxide which is then treated with sulphuric acid to form copper sulphate. By slow leaching in air of piles of low grade ore. Bacterial action is sometimes employed to hasten the process.

Copper Mineral

Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.

What Do Copper and Sulfur Make When They Are Heated up

Copper and sulfur make copper sulfide when they are combined. The copper must be in the form of a wire, and the sulfur must be in a hot gas form. Copper sulfide is created through hanging a piece of copper wire in a tube of boiling sulfur. The tube with the suspended copper wire must be clamped at the top and placed on top of a Bunsen burner.
