Copper slag, generated mainly during copper smelting, and classified as a potentially
harmful waste, is an important secondary resource containing not only valuable metals, such …

China's copper resources are characterized by low grade and complex composition. A large
amount of copper smelting slag (CSS) containing valuable elements such as copper and …

As a potential reusable resource, solid waste is gradually being used for extracting valuable
metals. In recent years, new technologies such as electrochemistry, supercritical fluids, ionic …

During mining, only 4–8% is converted to final products, and the rest is accumulated in
landfills. There is a lack of research on the study of various patterns and mechanisms of the …

Herein, the room-temperature sulfuric acid leaching of copper smelter slag powder in the
presence of potassium dichromate was investigated, resulting in the selective extraction of …

Over 50 million tons of copper slag are produced worldwide annually. Stacking is currently
the primary method used to treat copper slag, resulting in resource wastage and …

Metallurgical plants constituting of smelters and refineries recover metals (ie, copper) from
mineral deposits. Copper production generates several waste streams of which slag, sludge …

Attempts to economically and effectively treat copper slag (CS) and ferruginous manganese
ore (FMO) using the traditional direct reduction–magnetic separation process have faced …

The study evaluated the use of Lepidium sativum L. to assess the phytotoxicity of three types
of waste such as hazardous waste (slags from zinc to copper smelters) and nonhazardous …

Metallurgical slags are generated as a by-product of smelting during ironmaking,
steelmaking, and the production of ferroalloys and non-ferrous metals. The formation …
