In recent two decades, ultrasound has been broadly applied to the hydrometallurgical
leaching process to recover valuable metals within raw materials, aiming to solve the …

The state of the art for the recovery of metals from steel industry by-products using
hydrometallurgical processes is reviewed. The steel by-products are different slags, dusts …

Nano zero-valent iron (NZVI) with high chemical reactivity and environmental friendliness
had recently become one of the most efficient technologies for wastewater restoration …

Azo dyes are mostly toxic and carcinogenic and cause harm to humans and the
environment. This study was conducted to investigate the degradation of azo dye acid red …

Selenium (Se) is an essential trace nutrient for human beings, but excessive consumption is
badly toxic and causes specific harm. At present, with serious Se pollution to the water …

Blast furnace dust (BFD), a hazardous metallurgical waste, is generated during the iron-
making process and consists plenty of Fe and C. This study is among the first to apply BFD …

In this work, a novel composite, Ca (OH) 2 coated nanoscale zero-valent iron (denoted as
nZVI-Ca (OH) 2), was synthesized and used as an activator of persulfate for the degradation …

Because chalcopyrite leaching requires high oxidation and existences impurity
encapsulation, a new method for constructing an advanced oxidation system via an …

In this research, a composite electrode for blast furnace dust ash (BFDA) was proposed in
landfill leachate pre-treatment by Fe-C micro-electrolysis and electrocoagulation. To verify …

The novelty of deep reduction roasting is that iron (Fe) can be recovered to high degrees
and a large proportion of zinc and lead impurities can be simultaneously removed. In this …
