摘要： PURPOSE:To simply separate and recover each rare earth element and Y with good accuracy by bringing the rare earth element salt water solution into contact with extracting agent, stripping middle rare earth elements from the extracting agent, successively stripping heavy rare earth elements and Y and further, extracting the heavy rare earth elements. CONSTITUTION:The water solution of the rare earth element salts is brought into contact with the acidic phosphoric series extracting agent. By this method, Sm, Eu, Gd, Tb (middle rare earth elements) Dy, Ho, Er, Tm, Yb, Lu (heavy rare earth elements) and Y are extracted and while remaining La, Ce, Pr, Nd (light rare earth elements) in the water solution, they are separated and recovered. Successively, by back-extracting the middle rare earth elements from the above extracting agent with dilute mineral acid water solution, they are separated and recovered. Further, the heavy rare earth elements and Y are back-extracted from the extracting agent with the mineral acid water solution. This mineral acid water solution is adjusted for pH, and from this, the heavy rare earth elements are extracted with ternary saturated fatty acid series extracting agent, and while remaining Y in the water solution, they are separated and recovered. After that, by back-extracting the heavy rare earth elements from the above extracting agent with the mineral acid water solution, they are separated and recovered. By this method, each rare earth element and Y are continuously separated with good accuracy in a short time and the separation of the single element sat the next process is facilitated.

摘要： PROBLEM TO BE SOLVED: To effectively prevent leakage of an electrolyte to the outside of a system and thereby perform an activation process with a stable operation, by connecting an electrolyte reservoir container filled with an alkaline electrolyte to a battery lid and performing charge and discharge under the communication of the electrolyte in the battery with the electrolyte in the container when the battery containing the alkaline electrolyte is activated. SOLUTION: Before performing charge and discharge, an upper opening part (a part to which a safety valve is mounted after activation) of a battery lid is filled with an electrolyte, an electrolyte reservoir container of which upper part can be opened is connected to it, a condition that the electrolyte in the container sufficiently communicates with the electrolyte in a battery cell is confirmed, and thereafter, the charge and discharge are performed. For the method for connecting the electrolyte reservoir container to the battery lid, a method to connect the container to the battery lid with a screw-in type is more desirable than a method using an insertion type from a view point of prevention of electrolyte leakage in charging and discharging, and thereby, the container functions as a head tank and easily feeds the electrolyte into the battery cell.
