In this paper, the generation principle, distribution and related sites of waste heat in oxygen pressure leaching of refractory gold ore was studied. According to different gold ore and manufacturing technique, a waste heat recovery system was established, including waste heat cleaning, waste heat collection, waste heat transformation, waste heat utilization and other steps. This waste heat recovery system can maximize the recycling of waste heat of oxygen pressure preleaching process of refractory gold ore and energy saving and emission reduction, and enhance the adaptability and integrity of oxygen pressure preleaching process for refractory gold ore.
