Studies of Soils and Vegetation on Non-ferrous Metallurgy Slag Dumps

The influence of heavy pollution on the biodiversity of pioneer plant communities on the slag dumps of non-ferrous metallurgy and the floristic composition for abandoned copper ore deposits are noted.Practically all of the metals contained in the slag can be recovered. Go to recycling process. The special feature of LEGRAN’s metal slag processing system at the Lippe Plant is the way the material is treated. The slag and spent refractories need to be pulverised before they can be processed and this job is carried out by a rod and ball millMetal slag processing // REMONDIS´ Lippe Plant

Comprehensive Utilization of Copper Slag in a Pyro

Copper slag used in this study was cooled by water quenching, from a copper smelting plant, China Minmetals Corporation. The copper slag was first crushed and ground into −200 mesh powder before the experiment. XRF-1800 X-ray Fluorescence spectrometry (XRF) (Shimadzu, Japan) chemical analysis result is shown in Table 1. The Pilot plant tests have been conducted in a reactor with a volume of 8 m 3 for neutralizing Balkhash Copper Smelting Plant exhausted copper electrolyte. With addition of reduce slag in an amount of 250 g/dm 3 into the reactor for neutralizing electrolyte complete cementation of copper and arsenic has been achieved, and about 90% of iron Development of Technology for Recycling Copper Smelting

Characterization of copper slag for beneficiation of iron and copper

Globally a large volume of copper slag (Table 1) is produced which can be approximated to 2.2 tons of slag generated for every ton of copper produced [9].The annual worldwide production of slag is approximately 24.6 million tons in the early century [6, 7] and increasing at a rate of 11% per year [6].Table 1 illustrates the magnitude of slag is Asia, the continent with the largest production of copper slag in the world through producing 7.26 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 5.90, 5.56, 4.18, 1.23 and 0.45 million tons of copperEnvironmental and Socioeconomic Impact of Copper

Elements Distribution in Soil and Plants of an Old Copper Slag

The elements concentration in soil and accumulation in plants growing spontaneously on an old copper slag dump were studied. The research object was a landfill site of the Polevskoy copper smelter (Middle Ural, Russia), which is about 200 years old. We investigated composite samples, consisting of soil blocks (20 x 20 cm) with growing Ore reserves around the world are currently being depleted, with very few new discoveries occurring. This necessitates the search for the secondary sources of metals such as tailings [1,2,3,4], slag [5,6,7,8,9], and electronic waste printed circuit boards [10,11,12,13,14,15,16].Copper is one of the metals whose ore reserves have been Mineralogical Characterization of Historic Copper Slag to

Recovery of copper, cobalt, and zinc from copper smelter and converter

Recycling copper converter slag back to the flash furnace has been practised in some plants and it leads to an increase in the matte grade (Antonioni et al., 1981). In some plants, flash smelting furnace slag (1.6–2% Cu) and converter slag (5–7% Cu) are cleaned in an electric arc furnace, where coke is used as reductant and copper Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about 1.5 million tons of copper slag are generated annually in Korea. The oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe2O3), silica (SiO2 from flux), alumina (AI2O3), calcia (CaO) and magnesia A Study on Reduction of Copper Smelting Slag by Carbon for Recycling

Utilization of copper slag in cement and concrete

Copper slag is a by-product obtained during matte smelting and refining of copper. The common management options for copper slag are recycling, recovering of metal, production of value added products such as abrasive tools, roofing granules, cutting tools, abrasive, tiles, glass, road-base construction, railroad ballast, asphalt Extracting valuable metal is a common way of recycling copper pyrometallurgical solid waste (CPSW). However, its environmental effects are still unclear. This paper adopts a cradle-to-gate life cycle assessment to assess the impacts of recycling three main types of CPSW (smelting slag, copper ash, and anode slime).Life cycle assessment of valuable metal extraction from copper

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 Attempts have also been made by several researchers to prepare copper slag-derived ceramics [22][23][24][25].
