There has been a strong interest in technologies suited for mining and processing of low-
grade ores because of the rapid depletion of mineral resources in the world. In most cases …

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 …

Chalcopyrite is one of the most important copper minerals; however, the extracted efficiency
of chalcopyrite is still not satisfactory in hydrometallurgy owing to its high lattice energy …

Silver ion can be useful in improving chalcopyrite bioleaching efficiency. In this work,
leaching kinetics of this process was investigated using silver-bearing solid waste under …

A new set of metal–organic frameworks was designed by functionalizing g-C3N4 with
benzoic acid and using them as structure-directing ligands during the metal–organic …

Chalcocite is one of the most industrially valuable copper-bearing minerals available for
bioleaching. However, the efficiency of chalcocite bioleaching remains unsatisfactory. To …

Natural high grade chalcocite samples were leached in column under controlled Eh,
constant temperature and solution pH to investigate the effect of particle size on dissolution …

This study explores the influences of external iron ions on the dissolution behavior of
covellite minerals at different temperatures. External iron ions can significantly accelerate …

Being the main intermediate species, the performance of digenite (Cu1. 8S) and covellite
(CuS) crystallite in the leaching process of chalcocite remains unclear. This article …
