[et.al.] - A systematic review of sustainable gold extraction from raw ores using alternative leaching reagents. In: The Extractive Industries and Society, 2022, vol. 9, article nº 1010182214-790Xhttp://hdl.handle.net/10400.9/3892ABSTRACT: Drawing on recent experimental and commercial developments, this review reappraises potential substitute leach reagents for cyanide in the gold mining sector. In addition to extraction, the application of these reagents in the gold processing, pre-treatment and gold purification stages is explored. The main objective here is to discuss how the gold extraction process can be more sustainable, with a view to developing more greener leaching reagents.engMineral processingGoldHydrometallurgyLeachingSustainable solventsjournal article10.1016/j.exis.2021.1010182214-7918
