采用空气加压氧化法浸出富铜渣制备硫酸铜，通过试验确定了铜的最佳浸出条件。试验结果表明：在硫酸加入量为铜理论量的1．20倍、反应压力0．18 M Pa、浸出温度90℃、浸出时间3 h、空气过量系数1．6倍、液固体积质量比4∶1条件下，铜浸出率大于99．1％；浸出液通过除铁、蒸发浓缩结晶制得符合GB437-2009的硫酸铜；与空气直接氧化法相比，浸出时间缩短了3～4h，浸出效率大大提高。
採用空氣加壓氧化法浸齣富銅渣製備硫痠銅，通過試驗確定瞭銅的最佳浸齣條件。試驗結果錶明：在硫痠加入量為銅理論量的1．20倍、反應壓力0．18 M Pa、浸齣溫度90℃、浸齣時間3 h、空氣過量繫數1．6倍、液固體積質量比4∶1條件下，銅浸齣率大于99．1％；浸齣液通過除鐵、蒸髮濃縮結晶製得符閤GB437-2009的硫痠銅；與空氣直接氧化法相比，浸齣時間縮短瞭3～4h，浸齣效率大大提高。
