Copper slag waste has continued to cause increasing concerns due to the huge volumes
being produced annually worldwide. This paper presents a review of copper slag as a …

Various slags are produced as by-products in metallurgical processes or as residues in
incineration processes. According to the origins and the characteristics, the main slags can …

Zinc containing wastes/secondaries viz. zinc ash, dross, flue dusts, sludge, residue etc. are
generated in various chemical and metallurgical industries. The materials contain different …

In a race to save the earth of its rapidly depleting natural resources, the use of Secondary
Raw Materials (SMRs) as alternative replacements in several processes is currently …

Zinc and lead recovery from zinc plant residue (ZPR) has been investigated. The residue is
discarded as a cake from a Waelz kiln processing zinc–lead carbonate ores. The zinc plant …

Cu-slags are a by-product of pyrometallurgical processing and contain elevated
concentrations of metallic elements that may be released during weathering. Hence, they …

Nowadays, a higher demand on a lot of metals exists, but the quantity and purity of the ores
decreases. The amount of scrap, on the other hand, increases and thus, recycling becomes …

This review summarizes the results of studies on the selective dissolution and extraction of
Fe, Cr, Cu, and Zn by ionic liquids, as an alternative to the use of conventional molten salts …

Spent batteries contain hazardous materials, including numerous metals (cadmium, lead,
nickel, zinc, etc.) that are present at high concentrations. Therefore, proper treatment of …

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 …
