(46d) Potential to Recover Copper from Electronic Waste and
However, depending on the quantity of copper, the nature of its use, and the matrix it is embedded in, it may not be environmentally nor economically advantageous to recover the copper. At the same time global copper reserves are currently estimated at 2.1 billion tons of copper, with an estimation of undiscovered resources at 3.5 billion tons.

Extracting Copper from Ore: A Step-by-Step Guide
Copper ores can be divided into two main categories: oxide ores and sulfide ores, each requiring different extraction methods. Oxide Ores These ores, typically found near the earth's surface, contain copper in the form of oxides, carbonates, or silicates, such as malachite (Cu₂CO₃(OH)₂), azurite (Cu₃(CO₃)₂(OH)₂), and cuprite ...

Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated. The study of process mineralogy holds a significant ...

Copper Concentrate Enrichment Process
Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
