The history of pyrometallurgy can be traced back at least 6000 years to the simple copper smelters of present-day Israel (Themelis 1994) and likely some time later in China (Mackey 2014).Copper, silver and gold were the very first metals to be used by mankind, since they were originally found in their native metallic form.

The process isolates the impurities that concentrate in the molten zones, leaving the portions behind them somewhat more pure. This process is repeated until impurities are moved to the end of the rod and cut off, resulting in an almost completely pure metal rod.

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 bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
