  • SX Solvent Extraction of Metals: A Design Manual

    Copper Recovery by Solvent Extraction. A common method of copper recovery from oxide ores is dump leaching in which the excavated ore is crushed and dumped on an impervious surface in “lifts” of anything from 10 to 100 ft deep. Sulphuric acid is sprayed onto the levelled off dump via a network of pipes designed to give even distribution.

However, it is also known as a \"green\" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look. Beyond this, however, copper can truly be cited as the \"green\" metal both for its role in protecting the natural environment through its use in energy-saving applications See more on copper
