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 The metallurgical recycling of iron and copper from copper slag mainly depends on a transformation from nonmagnetic iron components (fayalite) into Comprehensive review on metallurgical recycling and
Details of the mainstream and recently developed routes for metallurgical recycling and further cleaning of copper slag are also summarised, such as flotation, From the annual Cu concentrate smelter production capacity, which is equal to around 21 Mt of copper metal in 2021, it can be estimated that more than 45 Mt Sustainable and Comprehensive Utilization of Copper Slag: A
Copper slag and RCA (recycled coarse aggregate) along with reclaimed asphalt pavement RAP materials have been used to achieve desired gradation of Copper slag, generated mainly during copper smelting, and classified as a potentially harmful waste, is an important secondary resource containing not only Comprehensive review on metallurgical recycling and cleaning of
Recycling copper slag using innovative technologies and circular economy practices could significantly improve the stability of cobalt and copper supply and could One of the most important goals of copper slag metallurgy is to minimize copper losses to slag from entrained Cu droplets during the smelting of copper Slag Metallurgy and Metallurgical Waste Recycling
than 40 million tons of copper slag is discharged into the environment worldwide[2] Dumping in specific landfill sites is still the main way to dispose of the copper slag for Copper slag waste has continued to cause increasing concerns due to the huge volumes being produced annually worldwide This paper presents a review of copper slag as a potential resource for cobalt and copper metals for a circular economyAn overview of the chemical and mineralogical characterisation of copper slag from 21 The potential for copper slag waste as a resource for a circular
Copper Slag of Pyroxene Composition as a Partial Replacement of Natural Aggregate for Concrete Production Copper slag, a byproduct of the pyrometallurgical process used for obtaining copper from copper ore in Bor, Serbia, contains mainly silicon, iron, calcium, and aluminium oxides Due to suchcopper slag increased compressive and tensile strength by 11% and 12%, respectively The increase of the replacement percentage of natural aggregate with copper slag gradually increased concrete density [19] Recently, copper slag has been used as a replacement for cement, eg, in the production of cement clinker [20,21], and as a Copper Slag of Pyroxene Composition as a Partial Replacement of
About 22 tons of copper slag are created for every tone of copper output The world copper sector has calculated that about 246 million tons of slag are produced Although copper slag is commonly utilized in the sandblasting business and in the production of abrasive equipment, it is removed without further reuse or recyclingAnnually more than 400 Mt of metallurgical slags are produced worldwide [1,2,3,4,5]From the annual Cu concentrate smelter production capacity, which is equal to around 21 Mt of copper metal in 2021, it can be estimated that more than 45 Mt of CUS were produced from primary sources assuming a slag to copper ratio of 22 [3, 4]Only Sustainable and Comprehensive Utilization of Copper Slag: A
recipients were Malaysia (41%), Indonesia (16%) and China (13%) Scrap tyre exports fluctuated9 The main recipients were India (46%) and Malaysia (29%) Exports of hazardous waste were reasonably consistent They mainly consisted of lead waste and scrap (74%) and leadcontaining slag, ash and residues (20%) The main recipient was Concrete technology is adopted worldwide in construction due to its effectiveness, performance, and price benefits Subsequently, it needs to be an ecofriendly, sustainable, and energyefficient material This is achieved by replacing or adding energyefficient concrete materials from industries, such as ground granulated blast furnace Destructive and NonDestructive Testing of the Performance of Copper
Synopsis Consolidating 125 studies undertaken since 1989, the effects of copper slag (CS) used as sand on concrete properties are discussed CS increases the consistence of concrete but, if uncontrolled, this may affect its stability The setting times and early strength development are retardedSteel slag is one of the most common waste products from the steelmaking industry Conventional methods of slag disposal can cause negative impacts on humans and the environment In this paper, the process of steel and steel slag production, physical and chemical properties, and potential options of slag recycling were reviewed Since steel Assessment of Electric Arc Furnace (EAF) Steel Slag Waste’s Recycling
Copper slag waste is considered a potential world resource owing to the huge amounts being produced annually worldwide which contain significant amounts of valuable metals (Phiri et al, 2021) The global copper slag production is estimated at 752 million tons for the period between 1999 and 2019 from the 13 main producing countries ventory assessment of recycling copper slag as building material in Singapore,” T ransactions of the Institute of Mea surement and Control,vol 35, pp 510–520, 2012LifeCycle Assessment of HighStrength Concrete Mixtures with Copper
Steel slag is one of the most common waste products from the steelmaking industry Conventional methods of slag disposal can cause negative impacts on humans and the environment In this paper, the process of However, this recycling method causes a waste of valuable metals since copper slag contains abundant iron and copper [1,2,5] Besides, the ceramics obtained from copper slag usually show red orTechnological behaviour and leaching tests in ceramic tile bodies
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 Kobe Steel continues to develop new technologies for the recycling of steel slag and dust as well as new uses for recycled material As a result, in fiscal 2014 Kobe Works, Kakogawa Works and Takasago Works limited waste consigned to landfills to approximately 80,000 tons Through operation of a newly established hotmetal treatment plantPromoting Resource Recycling || KOBE STEEL, LTD
The present research paper investigated experimentally the effective use of copper slag (CS) in recycled aggregate based selfcompacting concrete (SCC) The work is carried out in two series In the first series SCC mixes are prepared with recycled coarse aggregate (RCA) as a replacement of natural coarse aggregate of various Attempts have also been made by several researchers to prepare copper slagderived ceramics [22][23][24][25] However, this recycling method causes a waste of valuable metals since copper slagComprehensive review on metallurgical recycling and cleaning of copper slag
The circular economy changes focus on reusing, adjusting, renewing and recycling materials and products at the end of their service life From this new perspective, electric arc furnace (EAFRecovery of CuFe Alloy from Copper Smelting Slag Y Qu, K Tan, B Zhao, Sui Xie Materials Science Metals 2023 Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes However, the tailing slags still consist of 03–07 wt% Cu and 35–45 wt% prehensive review on metallurgical recycling and cleaning of copper slag
is Asia, the continent with the largest production of copper slag in the world through producing 726 million tons of copper slag per annum [22,23] Therefore, there is a need for utilization of this generated copper slag North America, Europe, South America, Africa and Oceania produced 590, 556, 418, 123 and 045 million tons of
