Extracting of Copper from Other Ores. Copper can be extracted from nonsulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.

Work was performed with surfactants developed by BASF specifically for heap leaching. Initial experimentation consisted of using flooded vats to compare copper extraction from ores. Leach solution with and without surfactant was fed to the ores. The presence of surfactants was noted to increase the overall copper recovered by approximately 23%.

Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be % to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined inhouse, or sold to custom smelters. The concentrate may be smelted to produce blister copper ...

The dilute copper grades contain small amounts of various alloying elements that modify one or more of the basic properties of copper. Electrolytic tough pitch copper C11000 is made from cathode copper, that is, copper that has been refined electrolytically. C11000 is the most common of all the electrical copper grades.
