It is desirable to remove arsenic from copper in the earlier stages of copper making due to the deposition of arsenic to cathode copper during the electrorefining process. Effects of temperature, flux, and oxygen on the distribution of arsenic during copper converting and fire refining processes were studied using FactSage 8.2.
The solid waste directly produced in the copper pyrometallurgy process mainly include smelting slag, copper ash and anode slime, which all contain a variety of valuable metals (Song et al., 2013). The smelting slag from the copper smelting process generally holds a certain amount of Cu and Fe (Li et al., 2021).

Pyrometallurgy focuses on the production of precious metal-loaded copper bullion from which high-purity copper can be extracted by electrolytic refining technique (Tuncuk et al., 2012). In this process, only a partial separation of metals is achieved, so other processes such as hydrometallurgy and electrochemistry are required ( Cui and Zhang ...

Pyrometallurgy is considered to be an environmentally friendly technology in processing of primary and secondary raw materials. The continuous development of pyrometallurgical processes to treat more complex raw materials requires direct support from fundamental research. In this reprint, 18 papers focusing on recent investigations into the existing and …
Despite the widespread and extended use of sensor systems in different industries, there is an important gap to reach equivalent conditions in pyrometallurgical processes for primary production. In the specific case of copper pyrometallurgy, the situation is particularly challenging to incorporate the Industry 4.0 concept for the …
Grinding and drying/de-watering- In the wet process, additives (olivine, dolomite and/or limestone depending on the end product) are ground and then added to the ore slurry, typically at a level of 3 to 3.5%, before de-watering. In the other process after hot grinding, the material is re-wetted in paddle-type mixers and combined with additives.
Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).
Based on the properties of the raw material, copper can be regenerated in three ways: (1) High-quality scrap copper is directly used to produce copper or copper alloy; (2) copper is produced by the smelting–pyrometallurgical refining–electrolytic refining process; and (3) for waste electronic materials with high content of precious metals ...
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.

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.

For copper sulfide ore, electrolysis is the final stage in the process of pyrometallurgy, in which anode copper slabs are hung in a large tank full of a copper-based electrolyte solution and an electric current is applied, resulting in the plating of copper onto 99.9% pure copper cathodes.
Advantages of Pyrometallurgy. Since Pyrometallurgy is a high-temperature technique, the reaction is quick. As a result, more metal is produced. The cost of reducing agents and raw materials is cheap.
