Low concentrations of manganese (0.01 M) can be selectively oxidised and precipitated from cobalt and nickel solutions at pH 3–4 with less than 1% co-precipitation of cobalt and nickel in the laboratory batch tests. The selectivity of manganese precipitation at pH 3–4 is consistent with thermodynamic data for the Mn–Ni/Co–H 2 O systems.
