Cuprion® Marine Anti-Fouling
WebProcessing. The recovery of cobalt from nodules has been studied and several methods and tests have been completed. These include Kennecott’s Ledgemont Laboratory’s Cuprion Process, developed in the 1970s specifically for recovery of metals from polymetallic nodules, as well as High Pressure Acid Leaching (HPAL), developed for processing … WebDec 10, 2024 · The Cuprion process faces issues with low Co recovery, slow reduction of the nodules by CO gas, and low value of the manganese residue. Sulfate processes derived from lateritic processes making use of autoclave leaching to reject Mn and Fe in the leach residue, face technological issues in the leaching, as well as poor valorization of the Mn. ... WebAmong all applied techniques, the Cuprion process developed by Kennecott Copper Corporation (KCC), and further improved by several researchers, has been found as the most promising method for recovery of metals from PMN. The process involves a reductive ammonia–ammonium carbonate leach in the presence of the reducing gas containing … rainha silvia jovem
