Pyrometallurgy is, however, today the traditional and most common approach for base metal and precious metal recovery from e-waste. Pyrometallurgy uses high-temperature processes in oxidative or reductive conditions to secure physical and chemical transformations in the raw material allowing the recovery of the metals of interest.

The Table 1 shows that the production of copper by hydrometallurgy with natural bluestone solutions is subject to fluctuation. At the beginning, the mines had a high output, but later, the output decreased with the decreasing bluestone solutions. After a few years, the output decreased significantly, and mines were gradually abandoned.

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.
A computer model has been constructed to simulate thermodynamically the behavior of the minor elements Zn, Pb, As, Sb, and Bi as well as the major elements Cu, Fe, Si, O, and S in the Isasmelt process, producing copper matte. The model is based on the new concept that there are two independent reaction sites in a slag bath: one for fast oxidation and the other for slow …
