摘要： PROBLEM TO BE SOLVED: To safely and efficiently recover and recycle various kinds of metals from wastes of battery packs of a primary battery and a secondary battery by immersing electrodes in acid liquid, eroding binder, and separating a collector and an active material from each other. SOLUTION: After discharging, a battery and a battery pack are disassembled and washed, an electrolyte in the battery is recovered, and ferrous components for constituting a housing are removed by selection with magnetic force. After that, recovering of various kinds of metallic compounds for constituting a collector of an electrode and the active material is performed by wet processing. The collector and an active material layer are impregnated in sulfuric acid or nitric acid. Therefore, acid enters between the collector and the active material, the collector is a little dissolved, and the active material is separated. The positive electrode active material is dissolved in acid, adjusted in pH, separated into Co and Li, and recovered. The collector is adjusted in pH with sulfuric acid used in the before process, and Al is recovered. Copper is recovered by electrysis. Moreover, the pH adjustment is performed, and Co and Li are recovered.

摘要： PURPOSE: To remove and recovery solder from a soldered article very easily, inexpensively, safely and perfectly by bringing the article into contact with an aqueous hydrogen chloride solution of a specified normality or below. CONSTITUTION: The article to be treated is cut so that the pieces may be so uniform in size that they are 5-20 by 5-20cm squares. It is necessary that the normality of the aqueous hydrochloric acid used is 11 or below, desirably 6-10. In order to shorten the dissolution time of solder, it is desirable that the contact with the solution is performed under heating. However, when the temperature is excessively high, substances other than the solder to be dissolved are dissolved and contaminate the treatment solution. It is desirable that the contact temperature is 40-80 deg.C. It is desirable that the contact is performed under pressure. Desirably, the pressure is 4-10kg/cm .G. The solid solder component is recovered, for example, by bringing the solder solution into contact with a metal having an ionization tendency higher than those of lead and tin or concentrating the treatment solution.

摘要： PROBLEM TO BE SOLVED: To concentrate impurities contained in a sample such as a semiconductor crystal without dissolving the sample, and to rapidly and simply analyze the conc. impurities in the sample with high sensitivity. SOLUTION: A predetermined position of a semiconductor crystal sample 11 is repeatedly irradiated with laser beam of a predetermined intensity by a laser oscillator 13 to concentrate impurities contained in the semiconductor crystal sample 11. Thereafter, the impurities contained in the conc. part of the semiconductor crystal sample 11 are analyzed with high sensitivity by a predetermined physical analizing means. If necessary, an insulating film pervious to laser beam such as an oxidation film is formed on the surface of the semiconductor crystal sample before concentrating impurities by laser beam irradiation.
