Acid Treatment The combination of hydrochloric acid and nitric acid have been found to be useful chemicals in the extraction of gold from ewaste Other mild acids have also been successful in their extraction of gold, as these acids can successfully dissolve gold while limiting their potential to cause adverse effects to the environmentGold extraction started in the fifth millennium BC However, in contrast to the long history of gold, the development of its chemistry was delayed because of its noble character Gold can be only dissolved in oxidizing media such as aqua regia or by complexing species such as cyanides under air 5 Long before the development of modern gold chemistry, the Gold Extraction an overview ScienceDirect Topics

This study presents the novel idea of a cyanidefree leaching method, ie, glycineammonia leaching in the presence of permanganate, to treat a lowgrade and copperbearing gold tailing Ammonia played a key role as a pH modifier, lixiviant and potential catalyst (as cupric ammine) in this study Replacing ammonia with other pH Roasting of complex gold ores, namely sulphides and carbonaceous (refractory gold ores), should take place before leaching in order to maximise the extraction ratio (Neuvonen, 2013) It should feature in cases where, even following long grinding processes, the exposure of gold to the leaching solution has been minimal (it, of course, A systematic review of sustainable gold extraction from raw
