In a race to save the earth of its rapidly depleting natural resources, the use of Secondary
Raw Materials (SMRs) as alternative replacements in several processes is currently …

Non-sulfide zinc deposits were the prime source for zinc metal production for hundreds of
years. However, during the early 20th century, their significance diminished due to the …

Cold sintering densification and coarsening mechanisms are considered from the
perspective of the non-equilibrium chemo-mechanical process known in Earth Sciences as …

This study was performed in two phases of work. In the first stage, alkaline leaching of lead
and zinc from an Iranian low-grade oxide ore was examined and the influence of the …

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 …

Copper anode slimes are essential secondary resources from which valuable metals, such
as Cu, Se, Te, Au, and Ag, may be recovered. Herein, oxidation pressure leaching is …

In this research, zinc, gallium, and germanium were selectively dissolved from zinc refinery
residue by stepwise leaching. The thermodynamic study demonstrated that Zn, Ga, and Ge …

The selection of acid type for metal dissolution from minerals is an important issue in
leaching operations. Acids are used to recover valuable elements from the minerals by …

The alkaline leaching kinetics of a zinc silicate ore assaying 34.1% Zn, 11.1% Fe and 22.9%
SiO2 is studied in sodium hydroxide solutions. Speciation diagrams indicate zinc dissolution …

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 …
