Schmitz et al. an alternative approach is to use melted paraffin wax which preferentially coats and blinds the preg-robbing carbon and then use conventional cyanide CIL circuit. It has been shown to work on a lab scale particularly where wax is added to POX in ores requiring a pre-treatment step in double refractory ores.ABSTRACT As the mining industry moves toward the extraction of increasingly complex ores to meet global demands,

Gold recovery from the cyclone underflow was targeted to recover as much gold as possible in the absence of the fine preg-robbing carbon. Gold is recovered by intensive cyanidation and tabling of aGold losses related to carbonaceous matter (CM) during processing are a significant problem in the gold processing industry. Inherent CM in gold ores can behave similarly to activated carbon in its ability to adsorb gold cyanide. This phenomenon is termed preg-robbing as the surface adsorbed gold cannot,
