The generation of tailings in the world today is immense, since only ounces or pounds of
metals are extracted for each ton of ore processed. In 2022, it was estimated that more than …

The interest in metal sulfide precipitation has recently increased given its capacity to
efficiently recover several metals and metalloids from different aqueous sources, including …

The efficient separation of metals from ores and secondary sources such as electronic waste
is necessary to realising circularity in metal supply. Precipitation processes are increasingly …

The ongoing depletion of gold and silver-containing ore deposits demands a shift towards
the processing of more complex sources. Leaching of gold or silver from these sources …

This paper presents studies on the possibility of utilization of technogenic waste from the
metallurgical industry by the method of complex processing in order to reduce the …

A novel eco-friendly synthetic gold lixiviant (Jinchan) was used to recover gold from gold
ores. Ultrasound was used to improve gold leaching efficiency and recovery percentage …

A hydrometallurgical process for the recovery of gold and silver from waste printed circuit
boards (PCBs) was experimentally verified and tested at pilot scale. The process comprises …

Gold is mainly extracted by cyanidation; however, cyanide is not only highly toxic to
organisms but is also not a very effective lixiviant for refractory gold ores. Environmentally …

A rapid photocatalytic gold recovery from the industrial cyanide-based gold plating
wastewater was carried out via TiO 2/WO 3 nanocomposites synthesized by hydrothermal …

In this study, a novel thiosulfate leaching system, cobalt-glycine catalyzed system, was
proposed. DFT calculations suggest that the coordination ability of organic ligands with …
