Copper Ore - an overview | ScienceDirect Topics
The principal copper ore mineral is chalcopyrite (CuFeS2), which is commonly smelted to yield a matte containing ∼50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).
Properties of Copper Ores - University of Arizona
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, covellite, and chalcopyrite are all examples of sulfide ores.

Copper Mining and Extraction Sulfide Ores
Copper minerals and ore are found throughout the Earth’s crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to make it commercially viable to extract the rock.
