Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.
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.
— Cu extraction from e-waste requires multi-stage processes in conventional pyrometallurgy or hydrometallurgy, followed by various downstream separation and recovery processes, including chemical precipitation, ion-exchange, adsorption, solvent extraction and electrowinning to recover Cu (Hsu et al., 2019; Li et al., 2018).

Within this paper, application options, the environmental behavior, and ways to treat copper slag in order to remove hazardous and recover valuable metals are critically reviewed.
— The Cu pyrometallurgy process treats Cu concentrates to produce Cu anodes that are then electro-refined by an electrochemical step in aqueous acid media. The Cu concentrates are copper and iron sulfide …
Conventional methods to extract copper from sulfide ores using pyrometallurgy have been used for decades and about 75% of primary copper is recovered using these methods [I]. Even though conventional processing is highly efficient, the depletion of clean copper sulfide ore reserves requires new strategies to extract the copper with certain ...
In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation). The gas phase may also be used to advantage, either as a means of separating valuable volatile constituents or for removing unwanted volatile impurities. These separation techniques form the basis of thermal smelting and refining …

— A combined hydro- and pyrometallurgy two-stage process was proposed to treat copper converter dust . The hydrometallurgical treatment by NaOH solution was undertaken for removal of sulfate sulfur and then carbothermal reduction of desulphated dust at 900 °C in a soda ash melt to recover valuable elements.
copper pyrometallurgy, expressed per ton of metal produced. It should also be borne in mind that the steel industry operates at a temperature higher than the temperature of the copper pyrometallurgy, at least 300 C and with more aggressive chemical systems. Even with the tremendous advance in the development of passive and active photonic
Pyrometallurgy is, however, today the traditional and most common approach for base metal and precious metal recovery from e-waste. ... High copper containing scrap is fed into the converting process directly, and low-grade e-waste is fed into the Kaldo furnace where an oxygen lance supplies the needed O 2 for combustion.
