Ozone has been proposed to pretreat refractory ores before the cyanidation process for precious metals extraction. As pyrargyrite is one of the silver species most common in Mexican refractory ores, the ozonization of this silver sulfide was studied. The effect of pH and ozone concentration on silver dissolution was evaluated by means of a factorial experimental design. Two levels of sulfuric acid concentration and ozone in gas concentration were evaluated: 0.18 and 0.72 mol/L of acid and 0.054 and 0.077 gO3/L, respectively. The highest silver dissolution was obtained when using the higher acid and ozone concentration.
