【摘要】 研究了焙烧—浸出法对中品位硫化铜矿的工艺条件，以及经铁屑置换制海绵铜（品位达８９％），再制取饲料级硫酸铜的工艺。通过适当的焙烧温度，可大大降低硫酸耗量，使铜浸出率达９８％，铜的总回收率大于９４％。更多还原

【Abstract】 The process for preparating feed stuff grade copper sulfate from copper sulfide ore by roasting-extracting method is studied.The result of test shows that the consumption of sulfuric acid can decrease greatly at proper roasting temperature,and the extracting rate and total recovery rate of copper can reach 98% and 94% respectively.更多还原
