In addition, iron arsenate was not considered sufficiently stable to exist within the environment, and it was mandated that arsenopyrite, which contained the gold, could not be chemically changed. Testwork was undertaken to develop a flowsheet that would maximise gold recovery from an ore containing 3 g/t Au and high levels of arsenic.
