Treatment of Refractory Gold Ores SpringerLink

Abstract. Problem ores that yield low (say less than 80%) gold recovery by cyanidation when normally ground are defined as refractory. The term, as well as the technical methods used to treat such ores, are relatively new. Rose and Newmans very comprehensive book, The Metallurgy of Gold, does not even contain the term refractory in its

Process for recovering gold from refractory sulfidic ores

Particularly in relation to the recovery of gold by cyanidation, it has been shown that the inventive nitric acid oxidation of a refractory ore enabled substantial recovery of the entrained gold. However, it was noted that in relation to arsenopyrite ores particularly, the recovery of gold by cyanidation following nitric acid oxidation was often only about 75% of the contained gold.
