center of the system. The copper ores are characterized by the following sulfide-bearing minerals: chalcopyrite, bornite and molybdenite (minor) with minor to moderate amounts of pyrite. These ore bodies are very large, generally containing from 100 million to several billion tons of copper ore with a copper content of 0.2% to 2.0%.

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.

Properties of Copper Ores The Problem 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.
