The purpose of this article is to explore potential solutions for hydrometallurgical processes
using semiconductor electrochemistry as an approach, that has received limited attention …

Rare earth elements (REEs) are abundant in certain mining coal, and further enriched in
coal fly ash (CFA) after coal combustion. If the appropriate leaching technology is chosen …

In this study, bacterial leaching of zinc, copper and antimony from tetrahedrite concentrate
was investigated with mixed mesophilic and mixed moderately thermophilic …

Currently, most of the methods for mineral materials analysis generate secondary pollution,
which is detrimental to human health. For instance, traditional methods for sphalerite …

The primary zinc ore in the world is sphalerite, and roasting-leaching-electrowinning (RLE)
is the most typical method of processing. This method has different disadvantages, and …

Due to the characteristics of simple process, environmental friendliness and low operating
costs, biometallurgy has become a popular technology for metals recovering from low-grade …

The roasting-leaching-electrowinning (RLE) process is the most common method for
processing sphalerite concentrate. However, this method has disadvantages that can affect …

The general trend in biomining (ie, bioleaching and biooxidation) is the use of media with
high concentrations of the nutrients (nitrogen as ammonium, phosphorous as phosphate …

Ferric leaching, including the oxidation of sulfide raw materials of nonferrous metals in a
ferric sulfate solution, is a well-known hydrometallurgical process that is widely applied in …

The generation of currently partially recyclable metallurgical dusts during the steel
production represents a challenge for the realization of a circular economy in this industrial …
