discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronzean alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.

The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it ...

Processes copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
The New Afton deposit is a silica-saturated, copper-gold alkalic porphyry-style deposit. The porphyry intrusive bodies can comprise stocks, plugs, dikes, and dike swarms with a footprint of typically less than one square mile in area. Mineralization results from late stage hydrothermal activity driven by remnant heat from the porphyry intrusion.
