Selective Flocculation of Chrysocolla Fines with Anionic Polyacrylamide/Acrylate Polymer

  • Y. Ye
  • M. C. Fuerstenau


Selective flocculation of chrysocolla fines has been examined with a variety of flocculants. Of those investigated, anionic polyacrylamide/acrylate polymers function the most effectively. The dissolution of cupric ion from the chrysocolla assumes a key role in flocculation behavior. Both chrysocolla and quartz/gangue are activated by hydrolyzed species of metal ions. Magnesium ion is found to adsorb specifically on chrysocolla and function as an activator under conditions in which significant hydrolysis of Mg++ does not occur.
