A nice introduction on the metallurgy of copper and other metals Smelting is a form of extractive metallurgy; its main use is to produce a metal from its ore. This includes iron extraction (for the production of steel) from iron ore, and copper extraction and other base metals from their ores. Smelting uses heat and a chemical reducing agent, commonly a fuel that is a source of carbon such as coke, or in earlier times charcoal, to change the oxidation state of the metal ore. The carbon or carbon monoxide derived from it removes oxygen from the ore to leave the metal. The carbon is thus oxidized in two stages, producing first carbon monoxide and then carbon dioxide. Copper is vital to modern life, since it is the basic materila for copper cables and a good electrical conductor. Therefore copper is mined extensively and extracted via various methodes. Some of the methodes are discussed in this book.

Sampling and Analysis of Copper Cathodes
Our little book review Sampling and Analysis of Copper Cathodes that was written by W. M. Tuddenham. This book discusses sampling and analyzing traceable impurities in electrolytic-type copper cathodes. The Papers do evaluate present and potential procedures for the sampling copper cathodes, including the drilling, punching, strip sectioning, milling, and saw-cutting of the copper cathodes. Sampling and Analysis of Copper Cathodes discuss methods of determining impurity levels and their accuracy.
