An color sorting technique was introduced to recycle End-of-life automobile shredded bumpers. The color sorting is a innovate method of separating the differences in the color of materials which are difficult to separate in gravity and size classification by using a camera and an image process technique. Experiments were planned and optimal conditions were derived by applying BBD (Box-Behnken Design) in the reaction surface method. The effects of color sensitivity, feed rate and sample size were analyzed, and a second-order reaction model was obtained based on the analysis of regression and statistical methods and R and p-value were 99.56% and < 0.001. Optimum recovery was 94.1% under the conditions of color sensitivity, feed rate and particle size of 32%, 200 kg/h, and 33 mm respectively. The recovery of actual experiment was 93.8%. The experimental data agreed well with the predicted value and confirmed that the model was appropriate.

Generally NiSO 4 and NiCl 2 were used as raw materials for producing nickel carbonate. In the case of the produced nickel carbonate, Na 2 SO 4 and NaCl are generated on the surface and inside of the nickel carbonate to decrease the purity of the nickel carbonate. High purity nickel carbonate can be produced according to the degree of removal of such impurities. In this study, NiCl 2 produced by nickel MHP solvent extraction process was used to study the production of nickel carbonate. High purity nickel carbonate was prepared by the conditions according to the nickel salt and carbonate equivalence ratio, the reduction of Na and Cl in nickel carbonate according to the washing of nickel carbonate, and the reduction of Na and Cl according to the washing water temperature.
