| Abstract: | Comparative experiment was carried out between two-step roasting and acidic pressure oxidation process on high-sulfur arsenic bearing refractory gold ore. The results show that the gold recoveries of two-step roasting and acidic pressure oxidation process are 88.59% and 95.6% respectively. According to the economic benefit assessment result based on the experiment gold recovery & operation cost, acidic pressure oxidation process is more advantageous for the high-sulfur refractory gold ore. |
