Bio-Oxidation Pretreatment of High Arsenic High Sulfur Refractory Gold Concentrate

Li Wanquan Zhang Yongkui Chen Ning Liang Ying Huang Yajie(Sichuan University)  
To extract the gold from a high arsenic high sulfur refractory gold concentrate of Guangxi,the gold concentrate was pretreated by bio-oxidation using Thiobacillus ferrooxidans in a foaming agitation cell test to decompose the pyrite and arsenopyrite so as to expose the gold for cyanide leaching.The effect of pH,inoculation concentration,pulp density,aeration amount and ore particle size on the bio-oxidation pretreatment process was studied.The results show that the appropriate conditions for the bio-oxidation pretreatment of this gold concentrate are: pH value of 2.0;inoculation concentration of 10%;pulp density of 100 kg/m3;and aeration amount of 0.1 L/(L·min).Under such conditions,the Fe and As leaching rates could be over 50% and 90% respectively after 10 d bio-oxidation.The smaller ore particle size is more beneficial to such pretreatment and the formation of the precipitation of ferric arsenate is unfavorable to the iron and arsenic leaching,which remains to be solved.
