Iron oxide copper-gold (IOCG) mineralization, first formally defined by Hitzman et al. (1992) and usually containing abundant (10%) iron oxides (magnetite or hematite) and economic grade Cu and/or Au (Williams et al., 2005), has been a major exploration target since the discovery of the enormous Olympic Dam Cu-U-Au (-REE) deposit in 1975.After the identification of Proterozoic

The Egyptian copper smelting process utilized a 'bowl furnace' which was supplied additional air, to raise the temperature of the fire, through the usage of foot bellows. Malachite and azurite were used as a source ore for the copper, charcoal was used as the reducing agent to separate oxygen from the copper, and iron ore was used as the

Ferrous and non-ferrous metals such as gold, silver, copper, bronze, zinc, aluminum and lead can all be easily melted by these induction melting machines. There is also the advantage of scalability, the metal melting furnaces can handle 250kg of metal in one melting operation and for smaller applications, it can also melt as low as 1kg.

According to the Law of Conservation of Mass, the mass of the products must equal the mass of the reactants, so logically one would expect that if 2 g of copper was used to start the lab, the lab would result in 2 g of copper. Unfortunately, that was not the case in this lab, and the final mass of copper exceeded the initial mass by 4.841g.
