Due to the advancement of industrialization and the development of the metal smelting
industry, cadmium (Cd), as a highly toxic heavy metal element, is discharged into the natural …

In this study, dissolution kinetics of nickel in sulphuric acid was investigated. The effects of
various parameters were studied to optimize the dissolution conditions and to determine the …

Copper and cadmium residue (CCR) is a hazardous solid waste generated in the process of
zinc hydrometallurgy, and contains large amounts of Cu, Zn, Cd and Pb. Recovery of Cu …

For the ever-growing demand of nickel (Ni) resources in industry, the Ni recovery from the
mining residues or waste has received considerable interest. Zinc plant residue contains …

Residues from the zinc roast–leach–electrowin process contain zinc mainly as finely
dispersed particles of franklinite. Thus, floatation, sulfuric acid leaching, and alkali leaching …

Soils contaminated with heavy metals represent a serious threat for humans and all
ecosystems. In some cases, they can be remediated by metal phytoextraction, using …

Solid residues from hydrometallurgical zinc plants contain high concentrations of heavy
metals such as zinc, cadmium and nickel, and these residues are considered as hazardous …

A large amount of Cu-Cd zinc plant residues (CZPR) are produced from the
hydrometallurgical zinc plant operations. Since these residues contain substantial amount of …

An intensified oxidative acid leaching of copper–cadmium-bearing slag featuring using high-
