Copper slag tailings, primarily stemming from pyrometallurgical processes, predominantly consist of a silicate matrix [].It is estimated that 2–2.2 tons of slag tailing are generated for every ton of copper produced, and approximately 40 million tons of slag are generated from global copper production [2,3,4].Unfortunately, slag tailings are often …
Copper slag (CS) is a solid waste produced in the process of copper smelting. Typically, CS contains about 30 − 45% Fe, 30 − 40% SiO 2, and other trace elements (e.g., Zn, Mo, and Pb) (Shibayama et al. 2010; Seyrankaya 2022; Gümüşsoy et al. 2023).According to statistics, with the rapid economic development, the annual output of …

The recovered Cu-rich slag (slag concentrate) is returned back to the smelting process, and the slag tailings would be the main output of As from the copper production system. To date, the slag tailings from the flash smelting enterprises are commonly dumped into landfill sites, while some studies have also proposed that the …
A pyro-hydrometallurgical process for the treatment of copper slag has been developed to accomplish recovery of nickel, cobalt, and copper and reuse of iron source. It was proved that the slag phase was reconstructed by sulfation-sulfate decomposition roasting followed by water leaching, over 95% iron existing as hematite …

Since the 19th century, copper smelting reverberatory furnace has developed rapidly. Modern large copper smelting reverberatory furnace (Fig. 1) is rectangular, and its internal dimensions are: 30-36 meters long, 7-11 meters wide, 3-4.5 meters high.It is built with high quality refractory materials, and its roof can be divided …
The mixture is heated constantly until it melts. Meanwhile, the molten impure metal is collected in the hearth which is thick and made of a strong material that can also resist any disintegration by the slag. The process …
The Okiep Copper District is located 600 km north of Cape Town in the north-western part of the Northern Cape Province, South Africa and includes the towns of Springbok, Okiep, Nababeep and Concordia.It is the oldest mining district in the country and has been a copper producer for more than 150 years.Copper smelters have been in …

The box shows the second and third quartiles, the line within shows the median, the dot the mean value. The whiskers show the minimum and maximum and hollow symbols show outliers. ... Mo is enriched during the copper processing in the slag if not removed from the sulfide concentrate. In the investigated heaps, not only the spinel …
Reverberatory furnace, in copper, tin, and nickel production, a furnace used for smelting or refining in which the fuel is not in direct contact with the ore but heats it by a flame blown over it from another chamber. In steelmaking, this process, now largely obsolete, is called the open-hearth
This research took the roasted products obtained by leaching copper (Cu) refining slag using waste acids and roasting leaching residues with calcium oxide (CaO) as raw materials and used oxidative leaching to extract Cu from roasted products using waste acids.

A technological scheme for copper slag processing is proposed. It comprises 5 stages, namely: (i) air oxidation of the copper slag at a temperature above 800 °C for 2 h; (ii) hydrothermal treatment of the oxidized slag with sodium hydroxide solution (140 g/l) at 190 °C for 3 h; (iii) separation of the solid from the liquid phase by hot …
Depending on the pyrometallurgical process used, copper slag can be divided into smelting slag, blowing slag, refining slag, and dilution slag. The growth rate in recent years would predict that the output of copper slag will exceed 24 million tons by 2020 (Fuentes et al., 2020).
Flotation is one of the most important methods for recovering copper from copper slag, However, traditional grinding may be over grinding sometimes, resulting in smaller interface difference, which leads to a decrease in the selectivity of flotation.
