Investigation of Gold Leaching in Thiosulfate-Based Solutions
In a 2021 study by Feng et al., the fundamental principles and process development of several major thiosulfate-based gold leaching systems were systematically reviewed.
The study provided a detailed assessment of the potential effects of various additives, including organic ligands containing amino, carboxyl, and hydroxyl functional groups, on gold leaching in thiosulfate solutions.
Furthermore, the study discussed the potential opportunities and challenges associated with the industrial development and application of thiosulfate-based gold leaching systems, highlighting their potential as an alternative to conventional gold cyanidation processes.
