Copper slag, a by-product of the pyrometallurgical process used for obtaining copper from copper ore in Bor, Serbia, contains mainly silicon, iron, calcium, and aluminium oxides. Due to such properties, it is disposed of in landfills. Despite the favourable technical properties copper slag aggregates possess, such as low-water absorption Global copper slag (CS) emissions reached 57.2 million tons in 2021. Despite the increasing reuse of CS, the treatment of CS is still dominated by landfill so far, which not only occupies land resources but also causes damage to the environment. The application of CS to cement-based materials (CBMs) is one of the main approaches to its Materials Free Full-Text A Review of the Influence of Copper Slag

The SEM results for copper slag show that the particle shape is irregular (i.e., angular) with the presence of sharp edges (Figure 3a). The elemental oxide composition of copper slag was obtained from the XRF analysis, and the major constituents present such as SiO 2 and Fe 2 O 3 are shown in Table 1. Moreover, the copper slag This paper summarized and reviewed the mechanism and macro-performance of alkali-activated metallurgical slag, including steel slag, copper slag, ferronickel slag, and lead-zinc slag. Better activated method and alkali-activator are still needed to be developed to improve the performance of the metallurgical slag with low Advances in Understanding the Alkali-Activated Metallurgical Slag

Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly Bottom-blowing copper smelting technology was initiated and developed in China in the 1990s. Injection of oxygen-enriched high-pressure gas strongly stirs the molten bath consisting of matte and slag. Rapid reaction at relatively lower temperatures and good adaptability of the feed materials are the main advantages of this technology. Metals Free Full-Text Development of Bottom-Blowing Copper

Copper slag has a granular consistency and is composed of crystalline particles. Copper has a dark hue and grain size comparable to river sand. Approximately 0.13% of the water that comes into contact with copper slag is absorbed. It has been demonstrated that slag contains less than 0.5% free moisture.Copper slag is generated when copper and nickel ores are recovered from their parent ores using a pyrometallurgical process, and these ores usually contain other elements which include iron, cobalt, silica, and alumina. Slag is a major problem in the metallurgical industries as it is dumped into heaps which have accumulated into millions Environmental and Socioeconomic Impact of Copper Slag

In order to maximize the utilization value of copper slag, a process of smelting copper–iron alloy with copper slag is proposed here. The reduction kinetics of copper slag by H2 are studied in this paper. The main phases of the copper slag were Fe2SiO4 and Fe3O4. The suitable conditions of reduction were a temperature of 1373.15 The research paper aims to explore the effect of copper slag on the characteristics of recycled aggregate concrete at high temperature. The behaviour of concrete has been examined experimentally by constructing recycled aggregate concrete using varying proportions (33%, 66% and 100%) of recycled coarse aggregate as natural Machine learning approach to study the mechanical

Copper slag (CPS) is a large amount of waste material produced during the manufacture of copper. The disposal of this waste material becomes a problem for environmental concerns. Therefore, it is necessary to explore feasible alternate disposal options. They may also be utilized in concrete manufacturing to cut down on the usage of The most suitable conditions for the reduction of copper slag comprised a temperature of 1450 °C, an alkalinity of 1.2, and a reducing agent ratio of 0.225. This newly developed process was found to recover 95.49% of copper and iron from the slag along with 83.54% of lead and 98.30% of zinc. You are accessing a machine-readable page.
