IPC: C02F1/70
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To individually recover copper, nickel and chromium from a ferric chloride waste liquor containing these metals to make the best use of these metals, and also to recycle a ferric chloride solution extremely low in impurity levels. SOLUTION: First, iron scraps are added to a ferric chloride waste liquor to reduce the ferric chloride into ferrous chloride. Secondary, in a copper- removing tank 31, such an amount of iron powder as to be 1.7 equivalent times the copper plus the same equivalent as the hydrochloric acid is added to the liquor along with adjusting the liquor to pH1.8-2.2 to effect deposition of copper which is then separated. Subsequently, in a nickel-chromium-removing tanks 51-53, such an amount of iron powder as to be 4-5 equivalent times the nickel is added to the resultant solution along with adjusting the solution to pH2.8-3.5 effect deposition of nickel and produce chromium hydroxide and iron hydroxide. Next, the nickel is separated from the system using a magnetic separator 42 followed by separation of the chromium hydroxide together with the iron hydroxide.  The resultant ferrous chloride solution is oxidized with chlorine gas, thus recycling a ferric chloride solution.
