Refractory Gold. Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind size can be considered refractory. The three primary factors that cause gold ores to be refractory are: • Physical encapsulation - Extremely fine (<10 µm) particles are locked within an impervious, unreactive mineral.
