    An evaluation of pretreatments to increase gold recovery

    Abstract The effect of three ore pretreatments on gold recoveries from an ore in which the gold existed in solid solution in an arsenopyrite matrix, as well as being encapsulated in a pyrrhotite phase, was examined. The three pretreatments evaluated includedfine grinding, pyrolysis-roast (Pyrox),and an oxidative pressure acid leach (PAL).
