Copper smelting slag (CSS) is a by-product of the modern pyrometallurgical copper production process, according to statistics, in the process of copper production, every output of 1 t of copper will produce about 2.2 t of the CSS(Du et al., 2023; Heo et al., 2016).
The effectivity of present copper smelting technologies have their roots in industrial and laboratory-scale experience accumulated over the past decades. Since early '60s, the tools for improving the processing conditions and smelting vessel design included scale modelling and manual computing of homogeneous multicomponent equilibria. The scale …
The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).
Along with actual evolution in the processing equipment, the basic metallurgy has been under careful evaluation and development. In spite of many favourable features of iron silicate slags, they become problematic in the direct-to-blister copper smelting environments, at oxygen partial pressures higher than in matte smelting.
The smelting process can be divided into three stages, namely decomposition of high-valence sulphide, oxidation of sulphide, and matte smelting and …
Waste electrical and electronic equipment (WEEE) represents a significant urban resource for precious metals.

Electronic goods are a major consumer of many critical metals, including copper, nickel, tin, zinc, lead, and precious metals. The processing of end-of-life electronic equipment (E-Scrap) is becoming increasingly important to maintain the supply of the critical metals required globally, and to reduce environmental pollution. Currently, the …
1. Introduction. Copper slag is a waste produced during pyrometallurgical processing of metals from copper concentrates. The decomposition and oxidation reactions of the sulphide minerals in the concentrate leads to the production of three separate phases: matte, slag, and an off-gas.
The copper content of copper slag is 0.5–4.5% or even higher, which is much higher than the 0.2–0.3% mining grade of copper mines in China.
Copper smelting slag is the largest solid waste produced in copper-making process, and slow cooling beneficiation technology is the most widely used method in recovering remaining treasures from the slag. The phase transition law and element distribution behaviors of the copper smelting slag in the cooling process have …

The smelting process produces a glass like substance that will settle on the top of the melting copper and is basically the non-copper impurities being separated. The slag is then skimmed off the melted copper and delivered to a "slag heap" or slag dump where it is left to cool. Once cooled the slag is broken up with heavy machinery ...
