Refractory Gold Ore
Refractory gold ore is generally defined as ore containing gold which cannot be satisfactorily recovered by conventional methods used to treat nonrefractory gold ores, like gravity concentration or cyanidation.. Cause . The refractory nature of these ores can be attributed to the presence of substances that consume the cyanide reagent before it can dissolve the gold, preferentially adsorb .

refractory gold ore
Refractory gold ores are those that do not yield high gold recoveries in conventional cyanideleaching circuits, even when the ore is finely ground. The cause of low gold recoveries can be either through the presence of naturally occurring 'preg robbing' carbonaceous materials or gold physically.
