Hydrometallurgy
Magnesium oxide is a key reagent for the proper performance of hydrometallurgy process. High purity Caustic Calcined Magnesite (CCM) is used to precipitate the hydroxide of valuable metals such as cobalt, nickel, uranium from acid leached solutions. Magnesium oxide provides an excellent metal recovery performance and increase in the precipitate grade. The advantages of caustic calcined magnesia also include a gradual and proper control of the pH. The metal hydroxide particles grow and settle out faster. The metallic sludge generated is more concentrated in the solid. The dewatering process is easier compared to a sludge produced with lime or caustic soda. For cobalt: Step 1. MgO + H2O→ Mg(OH)2 Step 2. CoSO4 + Mg(OH)2→Co(OH)2 + MgSO4
For nickel: Step 1. MgO + H2O→ Mg(OH)2 Step 2. NiSO4 + Mg(OH)2→Ni(OH)2 + MgSO4 |
