| Abstract: | In this paper the pretreatments of arsenical refractory gold ore with pressure oxidation process in an acid aqueous solution (H2SO4, HNO3-HNO3) and alkaline aqueous solution (NaOH, Ca (OH)2, NH4OH)have been shidied respectively. The experimental results show that the eganide leaching rate can be improved from 15%to over 85%by pretreatment of pressure oxidation. |

| Keywords: | arsenical refractory gold ore pressure oxidation follwed by aeid leach pressure oxidation followed by alkalige leaching |
