Copper slag was used as a raw material for building materials such as cement, concrete, glass and ceramic tiles, as well as for grinding and paving materials due to its excellent physical and mechanical properties . Copper slag produced in the smelting process contains a large number of valuable metals such as copper, zinc, cobalt, nickel and ...

Processed air-cooled and granulated copper, nickel, and phosphorus slags have a number of favorable mechanical properties for aggregate use, including excellent soundness characteristics, good abrasion resistance, and good stability (high friction angle due to sharp, angular shape).

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 of tons over the years.

Copper slag abrasive is dense enough to be reclaimed via a Cyclone separator in coarser sizes only. It has a 115 to 120#'s/cubic foot. THIS IS A HIGHER DENSITY THAN COAL SLAG (~20% HIGHER) AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL.

Physical properties of copper slag The physical properties of copper slag are given in Table 2. As seen, the density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3 that means copper slag is denser than ordinary natural aggregates.

Copper slag grit contains silicon and iron oxides. Copper slag is a by-product that is extracted during the smelting process and impurities become slag which is separated and used in other industrial processes. Copper slag grit contains a fine binding agent that holds the larger particles and improves the properties of the concrete.

12%Properties of waste copper slag Physical properties Copper slag grains have a color of black glassy type and a fineness modulus of 3.5. The hardness is about 7 Moh's scale. Other typical physical properties are given in Table 2.

Copper slag blasting. Abrasive shots Copper Slag is an aggressive abrasive frequently used in new steel and steel maintenance applications. Its bulk density and angular shape give it an aggressiveness that provides clean, fast-cutting action, considerably increasing production rates.

In recent years, a great deal of attention has been directed to the behavior of slags during pyrometallurgical processing of copper. This interest arises principally from the problem of losses of copper resulting from dissolved copper and entrained particles of matte and metal in slags. Also, slags are important in smelting and refining operations for many other reasons.

Copper slag properties in reverberatory furnace smelting, flash smelting, and other processes are similar. A typical smelting slag contains approximately 30–45% FeO, 30–40% SiO2, 5–10% Al 2 O 3, 2–6% CaO, and 2–4% MgO ( Kokal, 2006 ). Table 3.2 presents the wide-range chemical composition of copper slag from different sources.

Contractors may also use copper slag in place of sand during concrete construction. The slag serves as a fine, or binding agent, which helps hold the larger gravel particles within the concrete together. When used in this manner, the slag helps to improve the properties of the concrete, and also serves as a form of recycling.

Slag has similar properties to sand and is a very effective substitute during monsoon (rainy) season. Further, Copper Slag is also used in the production of cement, mortar, and concrete as a raw material for clinker, cement replacement, coarse and fine aggregates.

In this paper, the influence of heating up to 400°C on properties of the self-compacting concrete containing recycled copper slag fine aggregate was investigated. The residual mechanical properties such as compressive strength, splitting tensile strength, elastic modulus, and stress–strain curve of the heated concrete were measured with the ...

3.3 Copper slag Copper slag is a by-product material produced from the process of manufacturing copper. As the copper settles down in the smelter, it has a higher density, impurities stay in the top layer and then are transported to a water basin with a low temperature for solidification. The end product is a solid, hard

Mechanical properties of high-strength concrete incorporate copper slag as a fine aggregate and concluded that less than 40% copper slag as sand substitution can achieve high-strength concrete comparable to or better than the control mix, beyond which, however, its behaviors decreased significantly [1–3].

N2 This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to .

Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.

Abstract In connection with the development of copper and molybdenum production in Armenia, it becomes necessary to develop a technology for processing the slags of the functioning metallurgical plants to extract valuable metals from the slags.
