gold ores and subsequent precious metal extraction by cyanidation needs to be investigated. Dissolved arsenate and sulfate in the leaching solution must be removed to partially regenerate the NaOH and facilitate solution recycle to the oxidative leach. All waste products of the process would have to pass the
