Title:
スカンジウムの回収方法、並びにイオン交換処理方法
Document Type and Number:
Japanese Patent JP7276042
Kind Code:
B2
Abstract:
The present invention provides a method for recovering scandium from an acidic solution, which contains at least scandium, nickel and chromium, through an ion exchange treatment using a chelating resin, said method recovering high-purity scandium by suppressing adsorption of impurities onto the chelating resin. According to the present invention, a method for recovering scandium from an acidic solution, which contains at least scandium, nickel and chromium, comprises an ion exchange treatment step S2 wherein the acidic solution is passed through a column that is filled with a chelating resin, thereby having the scandium in the acidic solution adsorb onto the chelating resin and subsequently obtaining a scandium eluent. In the ion exchange treatment step S2, the length of move per unit time (linear velocity) within the column is regulated during the time when the acidic solution is passed through the column.
