Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores. Chalcocite, bornite, idaite ...

Copper isotopes can be successfully used to determine the origin of copper or bronze artefacts from either primary or supergene sulphide or hydrocarbonate ores. In conjunction with lead isotopes, they provide information on the origin and type of the metal ore. We demonstrate this in this paper from the combination of literature and own data on metal ores and artefacts (coins and ingots). Low ...

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3-8 m height after agglomeration and sprayed at flow rates of 6-40 L·hour −1 ·m −2 with 15-90 days duration for copper oxides and 10-18 months for sulfides. Of note, 80%-85% copper extraction was commonly achieved.
