Thiocyanate is among the most promising alternative gold lixiviants for gold leaching and
has not been extensively covered in the literature. Thiocyanate is 1000 times less toxic than …

The decreasing grade of gold deposits and environmental regulations concerning the use of
cyanide, a conventional extraction agent used in gold recovery, has highlighted the …

The leaching behaviors of gold and silver from a complex sulfide concentrate in copper-
tartrate-thiosulfate solutions were investigated in this paper. Experimental parameters …

Gold-bearing dust generated during the roasting process of refractory gold concentrates is
valuable as secondary gold resources. In this study, the characterization of gold-bearing …

In this article, the dissolution kinetics of pure metallic silver in acetic acid with a hydrogen
peroxide solution were carried out. The effects of stirring speed, acetic acid concentration …

The paper presents an overview of bio-oxidation of sulphidic refractory gold ores prior to
gold cyanidation. This review discusses several factors, more importantly, oxygen …

The process optimization and mechanism of microwave pyrolysis in a nitrogen atmosphere
were studied to improve the gold leaching rate for high-arsenic-refractory gold sulfide …

Stability of gold–polysulphide species was investigated using density functional theory
computations. Results showed that the stability of sulphur allotrope enhances with …
