 · Introduction. The use of acidophilic chemolithotrophic bacteria in pretreatment processes to degrade recalcitrant gold-bearing arsenopyrite ores and concentrates is well-established technology ( Brierley 1997; Dew et al. 1997 ).Recalcitrant ores are those in which the gold is encased in a matrix of pyrite and arsenopyrite, and as a result cannot be solubilized by direct cyanidation.
