Air-cooled and granulated copper slags have several favourable mechanical properties for use as aggregates in construction such as excellent soundness characteristics, excellent abrasion resistance and good stability (Gorai et al., 2003).These properties of copper slag make it suitable as a partial or full replacement for Portland …

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. In general, water absorption of …

1. Introduction. In the smelting and conversion processes of copper manufacturing, copper slag with 2–3 times of crude Cu is produced (Phiri et al., 2022, Zhou et al., 2022).Therefore, annual copper slag emissions have exceeded 50 million tons, even though the annual global Cu output is 23 million tons.

The main characteristic of COPPER SLAG has an hardness of 7 on the Moh's scale which ensures fast and easy removal of mill scale, rust and old paint coatings from steel and concrete – on steel upto the highest level of cleanliness (Sa3).

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 pavements.

Guorui Qu et al. [17] recovered Co, Cu, Ni, and Fe from copper slag in the form of alloys, which provided an opportunity for the recovery of copper from the smelted products to prepare high value-added products. Copper slag recycling has realized the transformation from shortening the process to improving the product value and economic …
