mechanical properties of copper ore

Properties of Copper Ores - University of Arizona

2005-3-7  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.
