摘要: The dissolution behavior of Caldag lateritic nickel ore subjected to a sequential organic acid leaching method was investigated. effects the type acid, concentration, time, and temperature on were examined. Organic acids used individually prior leaching. Citric more effective than other two for selective cobalt. An increase in citric concentration negligibly affected metals, whereas exhibited strong beneficial effect. Oxalic determined be most appropriate second step. After 8 h (4 + 4 h) with (0.5 M 0.5 oxalic) sequence at 90°C, 89.63% Ni, 82.89% Co, 69.63% Fe leached from ore. A oxalic could represent viable alternative metals
