オキシム－アミン混合抽出系を用いたコバルトの分離

Extraction behavior of cobalt from sulfate media containing excess manganese by mixtures LIX63 and several amines was investigated. The addition of amines shifted cobalt extraction isotherm to higher pH region in all case. The degree of the pH isotherm shifts depended on the basicity of each amine i...

Description
Summary:	Extraction behavior of cobalt from sulfate media containing excess manganese by mixtures LIX63 and several amines was investigated. The addition of amines shifted cobalt extraction isotherm to higher pH region in all case. The degree of the pH isotherm shifts depended on the basicity of each amine in the case of manganese however did not depend on it in the case of cobalt. The separation ability of cobalt from manganese was highest in case of LIX63 and primary amine system.
