Get Priceof CP150 and Kelex100 were required to completely extract copper, while only 1% of LIX984N was sufficient. Addition of hexane to the diluent decreased the capability of CP150 to extract copper, while it showed less effects on LIX984N and Kelex100. A desirable stripping of copper from the loaded organic phase could be obtained using H 2 SO 4 solution. Keywords: Copper, Ammoniacal Carbonate ...
Get Price· The copper (II) ion in the chalcopyrite is reduced to copper(I) sulfide which is reduced further to copper metal in the final stages. The iron in the chalcopyrite ends up converted into an iron(II) silie slag which is removed. Most of the sulfur in the chalcopyrite turns to sulfur dioxide gas. This is used to make sulfuric acid via the contact process (copper .
