abundance of copper ores


Posted on May 24, 2019



Copper Mining and Processing: Processing of Copper Ores .Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant,.abundance of copper ores,Copper: resource distribution,production and consumption, reserves .Copper in nature often exists in compounds. Currently, the explored copper is about 0.35-0.57 billion tonnes, and porphyry copper accounts for about 76% of total explored copper. Resources distribution in the world is as follows: Area distribution: Copper ore resources are abundant in the world, and mainly distributed in.
