(with picture)reaction at the surface is the rate controlling step since there is no internal diffusion limitation The model considering the effect of nonreacting gold shows that the reaction orders are consistent with the experimental observations reported by Ling et al (1996) and de Andrade Lima and Hodouin (2005) However, it should be noted that the model obtained in this work is based onMODELING OF GOLD CYANIDATION
