GCSE CHEMISTRY Extraction of Copper Thermal ... GCSE SCIENCE
Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper ( II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.

Like phytomining, bioleaching is a useful method for extracting metals from lowgrade ores. This is particularly important for copper, where highgrade ores are increasingly rare. It also uses less energy than smelting. However, some of the chemicals produced in the process are harmful, and the process is relatively slow and expensive.

Bioleaching. Bioleaching is the extraction of specific metals from their ores through the use of bacteria. They do this by producing leachate solutions that contain the metal compounds. A leachate is simply the solution we get when a liquid passes through an organism. The bacteria gets energy from the bond between copper and sulfur to separate ...
