World production data for slag were unavailable, but iron slag from blast furnaces may be estimated to be 25% to 30% of crude (pig) iron production and steel furnace slag may be estimated to be 10% to 15% of raw steel production. In 2021, world iron slag production was estimated to be between 340 million and 410 million tons, and steel slag ...

Copper slag used in this study was cooled by water quenching, from a copper smelting plant, China Minmetals Corporation. The copper slag was first crushed and ground into −200 mesh powder before the experiment. XRF-1800 X-ray Fluorescence spectrometry (XRF) (Shimadzu, Japan) chemical analysis result is shown in Table 1. The …

Steelmaking plants continuously strive to reduce the environmental load in the steelmaking process, resulting in the recycling of energy, water, and other byproducts. In this chapter, techniques for the treatment and recycling of metallurgical slags are described. Metallurgical slags are considered secondary raw materials and are used or …
