Metals | Special Issue : Advances in Pyrometallurgy
Garnierite is characterized by high magnesium and silicon contents. The main contents of garnierite are silicates, and nickel, iron, and magnesium exist in silicates in the form of lattice exchange. Silicate minerals are difficult to destroy so are suitable for smelting using high-temperature pyrometallurgy.

Comparative life cycle assessment of copper and gold …
For example, Li et al. [12] used LCA to compare the environmental impact of precious metal and copper recovery from electronic waste by three processes: (1) pyrometallurgy, (2) chemical leaching with conventional chemicals, and (3) chemical leaching with a novel copper leaching technique. We consider scenarios 2 and 3 to both …

Pyrometallurgy
Industrial grade pyrometallurgy is usually direct put the WPCBs containing 5%–40% copper into the blast furnace, and the product is black copper containing 70%–85% copper. The black copper is then poured into the converter, which makes an oxidizing slag of Pb, Zn, and Sn, and the copper that contains 95% copper content.

Chapter 6 Copper Production Technology
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.
