2021.10.14 The processing of Cu, Co, and Zn at the Boleo project in Mexico involves two-stage (oxidation–reduction) leaching to extract a total of 85–88% Cu in 4 h. The first stage is an oxidation leaching using sulphuric acid (120 kg/tonne ore) at an Eh of 900 mV for 2 h. Then, the reduction stage takes place in 2 h with SO2 gas sparging for Mn

Recent Progress in Hydrometallurgical Processing of Nickel
2022.8.22 The current literature reviews several processing aspects to address the extraction of nickel from laterite ore through hydrometallurgical routes. The following conclusions are summarized: Nickel is associated with cobalt in laterite oxide ores, and all the other Ni-based byproducts derive from Mg content.
