摘要
采用 NH3 — (NH4) 2 SO4浸取氧化铜矿 ,通过 (NH4) 2 S分离重金属 ,硫酸亚铁除砷等措施净化浸出液制备硫酸铜饲料添加剂 ,对浸取条件作了试验研究 ,对除砷机理进行了分析讨论。
A process for preparing forage-grade cupric sulfate from copper oxide ore containing arsenic was proposed.It includes copper oxide ore leaching with NH 3-(NH 4) 2SO 4 solution,separating heavy metals with (NH 4) 2S and removing arsenic with ferrous sulfate.The leaching conditions are researched and the mechanism for removing arsenic is analyzed.The advantages of ammonia and ammonium sulphate leaching are summarized.
