Leaching kinetics of copper from natural chalcocite in ...

1991-6-1  The leaching behavior of copper from natural chalcocite (Cu2S) particles in alkaline Na4EDTA solutions containing oxygen was examined at atmospheric pressure. The EDTA leaching process took place with consecutive reactions, where the solid product of the first reaction, covellite (CuS), became the reactant for the second. The copper leached into the

Copper Scrap - an overview ScienceDirect Topics

Copper scrap and metal-bearing precipitates are used rather than other copper-bearing materials. By leaching of copper scrap and metal precipitate (at 310–330 K, and maintaining the weight ratio of NH 3 to Cu + at approximately 4.2–4.3, with aeration), solutions with enhanced content of Cu (I) ions are obtained, thus requiring less sulfur ...
