Germanium as main raw materials of optical fiber cables become more important in recent years. Due to the scarcity and importance of germanium, we developing an effective recycling processes of recovering germanium metal from waste fiber optic cables. The process was arranged to do pre-treatment, leach the fiber and extract the germanium from silicon. In the leaching step, we dissolve fiber by alkali fusion using sodium hydroxide. At the solvent extraction process, the pH value, concentration of extractant and stripping agents, organic-aqueous ratio and reaction time were considered. After leaching, germanium was extracted by trioctylamine to the organic phase and silicon was remained in the aqueous by controlling the conditions. After then, Germanium was then stripped by ammonia. With the optimal conditions, the recovery of germanium could be up to 99%. After separation, germanium could be recycled to back to the industrial effectively.
