| Abstract: | 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. |
