The method of extracting cobalt blue pigment from acid waste lithium cobalt batteries and the optimum process parameters are studied. The results show that under the condition of pH 6, metalion and citric acid ratio was 1: 1 dry gel prepared at 135 ℃ cal-cination, then calcined at 800℃ uniform particle size, good dispersion and spinel structure of nano cobalt blue pigment can be directly synthetized.
