摘要： PURPOSE:To recover an alloy having the same purity as that of electrolytic metal from the scrap of maraging steel for its reuse, by removing Mo with a predetermined ratio or more from a liquid containing Fe, Ni and Co prepd. by dissolving the scrap of maraging steel in hydrochloric acid or the like, and then electrolyzing the residual liquid. CONSTITUTION:The cast flashes, machining chips, scraps or the like of maraging steel comprising Fe, Ni, Co, Mo, Ti, etc. are dissolved in dil. sulfuric or hydrochloric acid until the liquid comes in the vicinity of pH=1.5-3.5 at a room temp., for instance. Hence almost all of Ti is precipitated, while Mo is precipitated to a degree such that it remains at a ratio of 20-1,200ppm in the liquid depending on conditions. Thereafter, the precipitates are removed, and the acid dissolved liquid of Mo content at 0-6mg/l is electrolyzed. Consequently, a Fe-Ni-Co alloy having the same purity as that of electrolytic metal useful as a raw material for melting maraging steel requested to have high-grade quality is recovered.
