Calcium partition coefficient (K_pc) was 0.1707±0.0010 when using 12M HCl solvent and 0.0172±0.0001 for water solvent. For lithium, The K_pc found to be 0.0258±0.0002 and 0.0089±0.0001 while the separation factor (α) was 1.011±0.003 and 1.009±0.002 for the pure water and HCl solvent. The results showed dependency on acidity solvent, which can improve the mass production of enrichment.
