  Advances in the Cyanidation of Gold - ScienceDirect

  201611 · Cyanidation, a process used for over a century to extract gold from free milling ores, is so effective that it can economically treat low-grade ores (0.5 g/t Au). The concentration of cyanide added to dissolve gold is much higher than the stoichiometric requirement because of various interferences. The occurrence and composition of the …

  Bottle Roll Testing for Cyanidation of Gold Ores: …

  2021519 · Gold cyanidation in field scale is mainly conducted through heap leaching and tank leaching methods. The choice between alternatives depend on several factors including grade of precious metals in the ore, size of the reserve, etc. Regardless of the method selection, the liability of the Au-bearing ore to cyanidation is the most critical aspect.
