What is New Method for Gold Ore Preg-Robbing Analysis about?

This article proposes a new method for determining the preg-robbing potential of gold ores using standard additions of gold. Preg-robbing occurs when constituents in ore adsorb gold-cyanide complexes from solution, causing gold losses. The new method is compared to the industry standard Barrick Gold Mines test, showing good correlation for carbonaceous ores. However, for silicate and sulphide ores the Barrick test residence time is too short to reach equilibrium. The article discusses the mechanisms and cau
