The metal extraction from spent CMB catalyst using supercritical CO₂(scCO₂) was investigated with single organic system, binary organic system and ternary organic system to extract metal ions. Leaching solution of spent CMB catalyst containing 389 mg L^-1 Co²⁺, 187 mg L^-1 Mn²⁺, 133 mg L^-1 Na+, 14.97 mg L^-1 Ca²⁺ and 13.2 mg L^-1 Mg²⁺. The method consists of scCO₂/ligands complexation process and metal extraction process at 60°C and 200bar. The result showed the Co and Mn was selectively extracted from Mg, Ca and Na in the ternary system of mixture of Cyanex272, DEA and Alamine304-I.
