The demand for rare earth elements (REEs) has significantly increased due to their
indispensable uses in integrated circuits of modern technology. However, due to the …

Smelting activity by its very nature produces large amounts of metal-bearing waste, often
called metallurgical slag (s). In the past, industry used to dispose of these waste products at …

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

Metal leaching from metallurgical wastes (slags) by means of environmentally friendly
approaches is promising for practical applications. The goal of this study was to compare the …

Siderophores are a class of biogenic macromolecules that have high affinities for metals in
the environment, thus could be exploited for alternate sustainable metal recovery …

Petrological and geochemical approach was implemented to decipher red sandstone
dissolution under biotic conditions with bacteria, Pseudomonas fluorescens. Bacteria …

Three types of Cu-slags differing in chemical and mineralogical composition (historical, shaft
furnace, and granulated slags) and a matte from a lead recovery process were studied with …

Slags from metallurgical processes represent a potential resource of metals but also waste
materials that have not been successfully beneficiated to date. For this study, a bulk slag …

In many countries the use of lead-based ammunition is prevalent, and results in exposure
and poisoning of waterfowl and other species of birds. In waterfowl hunting areas large …

The selective sulfidation of lead smelter slag with sulfur was studied. The effects of
temperature, sulfur dosage, carbon, and Na salts additions were investigated based on …
