Abstract: | Metal-market analysts project a global nickel supply gap which will be filled by further high-pressure acid leach treatment of laterite ores and the commercialization of hydrometallurgical refineries to recover nickel from sulfide ores. The Activox® process is one such hydrometallurgical technology developed to recover a range of base and precious metals from sulfide ores and concentrates. The combination of ultrafine grinding and oxidative leaching extracted and enabled the recovery of 96.2% nickel, 88.3% cobalt, and 82.9% copper in the 310 kg/h Tati Hydrometallurgical Demonstration Plant. |
