Impact of Salt-Lake-Based Magnesia Reactivity to Cobalt Precipitation on Copper-Cobalt Mines, DRC

Key Points

• Cobalt precipitation levels were significantly affected by magnesia reactivity.
• Found that increased mineral reactivity can enhance cobalt recovery rates by up to 25%.
• Observational analysis across copper-cobalt mines in DRC evaluated the effect of magnesia on cobalt precipitation.
• These findings highlight the importance of mineral reactivity in optimizing cobalt recovery processes.
