摘要：
A process for the extraction of Co (III) from ammoniacal solutions comprising Co (III) and Ni (II). The process comprises:(a) contacting said ammoniacal solution with(b) bis (2,4,4-trimethylpentyl)phosphinic acid or an ammonium or alkali metal salt thereof,said ammoniacal solution forming the aqueous phase and said phosphinic acid, or salt thereof, forming the organic phase, and(c) a phase modifierwhereby the Co (III) values are extracted from said aqueous phase to said organic phase.
