【摘要】 硫化铜精矿经温和条件处理可提高铜的浸出率。温和条件为 :加热温度 140℃ ,加热时间 30h,硫酸和催化氧化剂对矿样的质量比分别为 1.1∶ 1和 1∶ 2 0 0 ;浸出温度 6 0℃ ,浸出液固体积质量比 6∶ 1,氧化剂和催化剂对矿样的质量比分别为 1∶ 2 5和 1∶ 2 0 0。按上述条件处理硫化铜精矿 ,铜的浸出率可达 97.42 %。更多还原

【Abstract】 Leaching rate of copper can be increased after copper sulfide concentrate being treated at gentle conditions that mass ratio of sulfuric acid and cat oxidant to ore is 1.1∶1 and 1∶200,respectively, heating time is 30 h at 140 ℃. Leaching copper from ore treated is conducted when leaching temperature is 60 ℃,V(liquid)/m(solid) is 6, mass ratio of oxidant and catalyst to ore is 1∶25 and 1∶200,leaching rate of copper can reach 97.42%.更多还原
