The total specific energy to concentrate copper to an average ore grade of 0.5% Cu from Thanatia was calculated as the energy in the ore handling process plus the energy required in its concentration, Fig. 3. The ore handling process included transportation of the ore with Thanatia composition to the concentration plant.

Reactions Involved in Iodometric Processes. Iodometric methods depend on the following equilibrium: [I_2 + I^- rightleftharpoons I_3^-] Since the solubility of I 2 in water is quite low, the formation of the tri-iodide ion, I 3-, allows us to obtain useful concentrations of I 2 in aqueous solutions. The equilibrium constant for this reaction is approximately 700.

Earth's surface. Prospecting for copper then was relatively simple. Recently, increased demand for copper resulted in numerous mines, and the search for copper ore is now very competitive. When a copper deposit is discovered, drilling is undertaken to determine the size and grade (concentration) of copper at the potential mining site.

The symbol and name for copper are from the Latin cuprum, which literally means "from the island of Cyprus", an early source of copper ore. Before 1982 U.S. pennies were pure copper. Now they are mostly zinc with a thin shell of copper. Most copper that is mined today is refined and drawn into wire for use in the electrical industries.
