| Abstract: | According to NiPt target materials, the selective dissolution-neutralization precipitation process was used to recovery nickel and the process of aqua regia dissolving-removal of impurities by oxidation hydrolysis-ammonium chloride precipitation-calcination was used to recover platinum from the Pt-enrichments. The results show that, under the conditions of sulfuric acid concentration 40%, temperature 85 °C, time 4 h, liquid-solid ratio 4, the nickel dissolved rate is greater than 99.4%, nickel recovery more than 99%. Pt-enrichments was treated by aqua regia dissolution, oxidation hydrolysis, ammonium chloride precipitation, and calcination, a platinum sponge with over 99.5%recovery and 99.99% purity was obtained. |
