- •
A spent CMB catalyst was completely leached at 1 M H2SO4, 40 °C and 0.1 of S/L ratio.
- •
The S × F value of Co and Mn over Ca and Mg was higher than 11 by Na-Cyanex 272.
- •
Co and Mn was recovered from Ca and Mg through 4 stage extraction by Na-Cayenx 272.
- •
Re-manufactured CMB contains 48.5 g/L Co and 23.2 g/L Mn by 2 M HBr in stripping.
- •
In pilot plant, 288 L CMB liquid catalyst could be produced during 24 h.
