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.
Pyrometallurgy deals with chemical reactions at high temperatures (ranging from 100°C up to 3000°C). These reactions involve numerous different solids, liquids, and gases, and are …

This process consumes 2,500 to 3,000 kWh · t –1 of copper produced. The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method …
Copper Ores - Raw Materials of Pyrometallurgy. Air, which entered the blast furnace at the bottom after preheating, is also an important raw material; it is required for combustion of the coke. Production of 1 kg of crude iron, called pig iron, requires about 2 kg of ore, 1 kg of coke, 0.3 kg of limestone, and 1.5 kg of air.

The Chilean copper mining industry currently consumes approximately 4.1 m3/s of seawater, which corresponds to 25% of the total water used. The use of seawater for the leaching of copper sulphide ...
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 …

World copper mine output in 2002 was 13.3-million metric tonnes and is anticipated to reach 14 million by the beginning of 2004. Present global land-based resources are projected at 1.6-billion tonnes of copper while deep-sea nodules …
With the rapid development of industry in China, China has become the largest producer of refined copper as well as the largest consumer of copper in the world. In order to provide the support for decreasing the environmental impact of the copper pyrometallurgy of China, the life cycle assessment methodology was carried out in this study to identify and analyze the typical …
Printed circuit boards (PCBs) make up a substantial amount of electronic waste (e-waste) generated annually. Waste PCBs contain high quantities of copper and gold in comparison to natural ores. As such, "urban mining" of waste PCBs to recover these metals is of commercial interest. In this work, we used life cycle assessment to compare the […]

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.

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.

CHAPTER 04 Nonferrous Pyrometallurgy INTRODUCTION Development of continuous copper matte converting processes creates a strong demand for continuous copper fire refining. Copper refining requires two stages: oxidation with slagging of impurities and sulphur removal, and copper reduction before anode casting.
