If you do not see your copper byproduct listed please contact Cal-Chem Metals to learn more about our services and custom solutions. Fine copper slag has reportedly been used in HMA pavements in California and granulated copper slag has been incorporated into asphalt mixes in Georgia to improve stability. By continuing you agree to the use of cookies. Copper Slag is a by-product of copper extraction by smelting. Often rightly so, since the high heavy metal content does not allow its use as a mineral product. Copper slag is a by-product of copper extraction by smelting. Data from Ahmari, S.; Parameswaran, K.; Zhang, L., Alkali Activation of Copper Mine Tailings and Low-calcium Flash-furnace Copper Smelter Slag. Copper is a heavy metal that is a commodity on many markets. If you or a person you know can answer yes, you really need to read and share the below article that was published on The Baltimore Sun's front page, by Tim Wheeler, titled "Federal agency investigating sand-blasting hazards Contaminants in coal and copper slag pose risks, critics say.". When the mines aren't careful, the sulfuric acid will leach into surrounding streams and cause major problems among the fish, wildlife, and plant communities. It is composed of ferrosilicate material and oxide when the slag is quenched in the cold water. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. This is helpful, as it supports the simple and empirical model used to explain the change in strength with increasing CS content. The slag serves as a fine, or binding agent, which helps hold the larger gravel particles within the concrete together. ScienceDirect ® is a registered trademark of Elsevier B.V.

Figure 5.11. ; Seal, R.R., Characteristics and Environmental Aspects of Slag: A Review. When mines extract copper, they often use sulfuric acid, which helps to separate the ore from the rest of the surrounding rock. Copper slag is a hard, cubical, and aggressive sandblasting media. Currently, CKD waste is generally excluded from the definition of hazardous was… copper slag corresponds to 30–40 % iron, 35-40% silica, less than 10 % of alumina and calcium oxide and copper content is around 1 %Cu, similar to the ore mined. Copper slag is mainly used for surface blast-cleaning. Under a constant water/cement ratio, with a given set of materials, and in the absence of particle size distribution data for the two sands, such a variable strength response with increasing CS content is most likely to be the outcome of varying particle packing, with the positive effect of CS as a sand material at a certain point (in this case up to 50/50 sand/CS content), being gradually eroded, and beyond a certain content (in this case 80% CS) it enters the negative field. I believe most of the problem is not with the ore itself, but with the process that removes the ore. Characteristics and utilization of copper slag—a review. Pune, Maharashtra, India, December 30 2020 (Wiredrelease) Prudour Pvt. Figure 7.13. I was also curious how the copper slag can be less harmful for your health compared to silica. Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Copper slag is a by-product created during the copper smelting and refining process. Black, glassy, more vesicular when granulated. http://dx.doi.org/10.1061/(ASCE)MT-1943-5533.0001159, Copper Slag in Cement Manufacture and as Cementitious Material. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. This material also has several limitations that users should be aware of before using copper slag. Copper slag can also be used as a building material, formed into blocks. Indeed, this is likely to be the main contributor to the variable trends observed in the strength data provided in the literature, and this can clearly be seen from all the data presented Table 4.3 in two forms, namely the studies where, perhaps prudently, the two sets of mixes, CS mix and the corresponding reference mix without CS, were made to have the same consistence, and these results are presented in Table 4.3(a), and where the water/cement ratio was considered as the prime factor and kept constant, even if the consistence was to vary, and these results are presented in Table 4.3(b). 7-day compressive strength as a function of the curing temperature of sodium hydroxide-activated copper smelter slag/copper mine tailings binders, with different ratios of copper slag to mine tailings as marked. Figure 4.7. Kedia slag distinguishes from light-weight blasting slag, due to its high density property. These materials are usually fine, but when they react with water thanks to the mine opening, they can turn to liquid form and create dangerous chemicals that also run into the water system. Typical physical and mechanical properties of copper slag. Typically it is composed of Ferro silicate material and oxides formed when the molten slag is quenched in cold water. However, the few studies evaluating the influence of using ground CS with different production methods on the properties of mortar (Douglas et al., 1986) and concrete (Mohsenian and Sohrabi, 2009a) have produced inconclusive results as shown in Figures 5.11 and 5.12. Is this right? Kleen Blast Copper Slag is Washed before screening which helps to minimize the abundance of … Quenched CS would be expected to outperform air-cooled CS when used as a cement constituent, based on its mineralogical composition and especially its amorphous material content (Chapter 3). It may also contribute to pollution and other environmental concerns. (2009a) because of a possible compaction problem in concrete due to low slump and Sudarvizhi and Ilangovan (2011, 2012) for using copper slag in conjunction with ferrous slag. Clearly, given the information available in the literature, there is scope for a fundamentally important study to be conducted to investigate the amorphous nature of the quenched glass and its pozzolanic reactivity, the variability attached to it and what benefits, if any, can be derived from it. Copper slag has also gained popularity in the building industry for use as a fill material. Using blasting or high-pressure spraying techniques, companies can use copper slag to clean large smelting furnaces or equipment.
