中文摘要：
以低铁闪锌矿精矿为原料,采用氧压浸出技术进行处理。绘制了150℃、1.0 MPa的ZnS-H2O系电位-pH图。通过单因素试验确定各因素的影响趋势,采用ICP、XRD、XRF和BET等检测方法对浸出液和浸出渣进行分析表征,确定最佳浸出条件为：精矿粒度-0.075 mm～＋0.055 mm、浸出温度150℃、氧分压0.8 MPa、初酸浓度15%、浸出时间90 min、浸出液固比6∶1～8∶1、搅拌转速500 r/min、添加剂用量1.0%。在此条件下,锌浸出率在97%以上,硫转化率达到90%,实现了精矿中锌的充分浸出与渣中元素硫的富集。
英文摘要：
Oxygen pressure leaching process was applied to treat low iron sphalerite concentrate.Eh-pH diagram of ZnS-H2O system at 150 ℃ and 1.0 MPa was drew.The single factor experiments were performed in autoclave,the leachate and residue were characterized by ICP,XRD,XRF and BET.The results indicate when particle size is-0.075 mm～＋0.055 mm,temperature is 150 ℃,oxygen partial pressure is 0.8 MPa,initial acid concentration is 15%,leaching time is 90 min,leaching liquid-solid ratio is 6∶1～8∶1,stirring speed is 500 r/min,and additive amount is 1.0%,extraction rate of zinc is above 97% and conversion rate of sulfur is about 90%.Sufficiently leaching of zinc and enriching of element sulfur in the residue were achieved via the process.
