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.

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.

Cement, one of the main components of concrete, poses environmental risks, accounting for 7% of total global carbon emissions. To alleviate the environmental hazards related to cement manufacturing, …
Concrete is the most produced construction material in the world and has a close tie to carbon dioxide emissions. To reduce the gas pollution and resource drain of cement production and utilization, researchers have replaced some of the cement and natural aggregate content with industrial by-products such as steel slag, ferronickel …
1. Introduction. Copper is an indispensable basic raw material for modern industry, however, the grade of copper ore is relatively low in China for the reason that the copper mines are dominated by lean ore, associated ore, and symbiotic ore, especially in the process of smelting it is necessary to add fluxes such as calcium oxide and silica, …
In spite of the considerable research on the mechanical and durability properties of geopolymer concrete, its widespread applicability is hindered due to the difficulties involved in achieving ambient curing conditions and awareness of the effective utilization of industrial by-products. This study investigates the physical and …
In cement industry, copper slag can be used as raw material for cement production and mineralizer for cement clinker production. Copper slag can mix and ground with gypsum and cement clinker to produce cement. This process uses a large amount of copper slag (about 60–70% of the total cement raw materials), and energy …
tonnes of copper slag is generated. It has been estimated that approximately 24.6 million tons of slag are generated from the world copper industry (Gorai et. al. 2003). Although copper slag is widely used in the sand blasting industry and in the manufacture of abrasive tools, the
Copper slag is one of the mining wastes that is raising growing concern due to the huge volumes being produced and dumped annually worldwide. These huge …
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 …
