How to Do Cyanide Removal in Gold Tailings? CNFREE

24/07/2020 There are many methods for cyanide removal in cyanide tailings of gold mines, but most of them require higher investment or advanced technology, and need to increase the investment in the gold cyanidation plant. But there is a more convenient method that can save the process of cyanide removal, which is choosing eco-friendly agents for gold extraction. CNLITE gold dressing agent is such a eco

Applicability of gold tailings, waste limestone, red mud

01/12/2018 The gold-containing ore is found in sulfide form and mineralization of gold tailings causes environmental contamination by releasing acidic effluents and leaching of cyanide complexes (Ritcey, 2005).
