Over the past years, persulfate (PS) is widely applied due to their high versatility and efficacy
in decontamination and sterilization. While treatment of organic chemicals, remediation of …

This article presents the mineralogical and chemical characteristics of zinc and lead
smelting slags, with particular reference to the slags formed during the simultaneous …

Germanium-containing dust as an intermediate by-product in the process of zinc
hydrometallurgy, which often contains a large number of heavy metal substances. Due to the …

This paper presents a study for leaching kinetics of sphalerite concentrate in FeCl3–HCl
solution. The shrinking core model was applied to the results of experiments investigating …

The leaching kinetics of zinc residue, having total Zn content of 12.31%, along with other
metallic components such as Fe and Pb, is leached using sulfuric acid as solvent …

This work examines the dissolution kinetics of an iron–rich zinc sulphide concentrate in acid
ferric sulphate medium. The effects of temperature, ferric ion and sulphuric acid …

This paper presents a novel methodology to recover gold from waste electrical and
electronic equipment (WEEE) using ammonium persulfate ((NH 4) 2 S 2 O 8). Gold was …

Mixed sulphide–oxide lead and zinc ores are most often found in the transition, and
occasionally in the oxidised, zones of lead–zinc ore-bodies. They are of great importance …

This work sought to integrate bioleaching and chemical leaching as a cost-effective process
to treat zinc sulphides. The continuous bioleaching of a sphalerite concentrate, assaying …

The kinetics of dissolution of sphalerite with hydrogen peroxide in sulphuric acid solution
was investigated. The influence of stirring speed (0–600rpm), dissolution temperature (10 …
