The targeted arseniferous solutions in this study were gold cyanidation process waters after destruction of cyanide. Based on a survey of several gold processing

  • Gold extraction Wikipedia

    A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A
