1. Introduction. Carbonaceous gold ores are considered problematic as the native carbonaceous matter within the ore acts as a sink for the gold cyanide complex, competing with the added activated carbon during leach and recovery operations (Pourdasht, 2018).These ores are commonly called preg-robbing as the Au cyanide …

The average grade of gold ores has been falling over the years. Between 1830 and 1900, the average grade of gold ore was around 20 g/ton and in 2000; it had dropped to around 3 g/ton (Muller and Frimmel 2010). Gold mining companies are processing lower grades of ore as the higher-grade ores are getting depleted.
