The membrane process achieved high water fluxes (15.5 ± 0.2 L⋅m − 2 ⋅h − 1 ), salt rejections (98 %) while precious metal recovery (91 %) was achieved through adsorption processes [15].
The pyrometallurgy-based method is favored for commercial use due to its straightforward process, ease of scalability, and flexibility in handling various battery types [7]. In this review article, the pyrometallurgy processes for spent LIBs recycling are reviewed with great attention to the last results and improvements.
Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi …
This chapter describes pyrometallurgical processes to recover metals from WEEE, such as waste printed circuit boards. Furthermore, it discusses their advantages, limitations, and associated challenges. Further details on the copper- and lead-smelting strategies used to recycle e-wastes are also presented.
The study by Villares et al. [6] presented a copper bioleaching process that is comparable to the parallel process in our LCA, and the authors also compare their results to data from Ecoinvent that they used to evaluate copper pyrometallurgy. They found that the bioleaching process with 10 % PD. Conclusions
Considering that the low recovery efficiency and the massive loss of valuable metals by the traditional pyrometallurgical process smelting low‒nickel matte. Therefore, this paper focuses on ...

The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel.
The metabolism of copper and arsenic in a copper pyrometallurgy process was studied through substance flow analysis method. The mass balance accountsand substance flow charts of copper and arsenic were established, indicators including direct recovery, waste recycle ratio, and resource efficiency were used to evaluate the …
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.

Various aspects of the engineering of these treatment methods are ... forming process and reduce the electrical conductivity of copper. The maximum allowable
There are several major megatrends having an impact on Pyrometallurgical metals processing. The steadily growing demand for all metals is strengthened by the emerging of electrical vehicles (EV) which …
Pyrometallurgy is a metallurgical process used to extract metals or their compounds from metallurgical raw materials or to refine them at high temperature. ... (such as copper and nickel), or some isolated pyrometallurgy processes can be adopted in the process dominated by other processes. In metallurgical production, all steel and iron, …
Typically, the objective is to recover valuable materials from LIBs, particularly from the active materials in the anode and cathode, using pyrometallurgical and/or hydrometallurgical processes ...
If pyrometallurgy is unavailable, we recommend either the chemical leaching process or the bioleaching process at 10 % PD. As with the combined process for copper and gold recovery, bioleaching of copper at 1 % PD leads to significantly greater environmental impact in comparison to the recommended processes. 4.
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 …
Pyrometallurgy is, however, today the traditional and most common approach for base metal and precious metal recovery from e-waste. ... The copper matte containing precious metals is removed and transferred to the converters. After an upgrading in the converter, liquid blister copper is refined in an anode furnace and cast into anodes with a ...
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.

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 level of process complexity in pyrometallurgy can often seem daunting. Although it is tempting (and instructive to a degree) to isolate and study individual parts of the physics and chemistry on their own, important coupling and interaction effects between various phenomena may easily be missed in this way. ...

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).
