Smelter slag is initially deposited in piles. These slag piles range in surface area from one to 75 acres, and in height from three to 45 meters. Slag is associated with smelter operations, which may or may not be co-located with the mines. Copper slag can be used either as sandblast grit or an additive to concrete.

The copper slag produced by the smelting industry contains valuable metals like Cu, Fe, Zn, Pb, Co, and Ni, along with harmful components like As, Hg, Bi, and Sb. However, over 80% of global copper slag is discarded without proper disposal, wasting valuable metals and harming the environment (Phiri et al., 2022). While some copper …
One such waste dumped material; copper slag is used in this research investigation for its feasibility in using as an inert material in concrete production. Copper slag is obtained from the copper manufacturing industries as a by-product in smelting process [7]. One tons of copper produces 2.2 tons of waste deposit as a copper slag.
This research study reports the potential use of copper slag as a replacement for sand in concrete mixes. Many countries are witnessing a rapid growth in the construction industry, which involves the use of natural resources for the development of infrastructure. This growth poses a threat to natural resources that are available.
The load resistivity of copper slag allowed it to be favourable for cutting non-ferrous metals, wood or plastics. W. S. Inynierska [109] reported that copper slag could be an efficient binder instead of ceramic binder in grinding wheel manufacturing. Improved grinding efficiency and decreased energy consumption were obtained by improving the ...
Most of the studies observed that up to 15% by using the weight of copper slag as Portland cement replacement improves in stress due to declining capillary porosity related to hydrated lime and 40–50% and 40–60% (by weight of sand) of copper slag can be used as a substitute for fine aggregates and coarse combination concrete is …
potential applications for reusing copper slag is in cement and concrete production. Many researchers have investi-gated the use of copper slag in the production of cement, mortar, and concrete as mixed with lime stone powder, dust, cement replacement, use as partial replacement of coarse, and fine aggregates. The use of copper slag in

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste footprint.
