摘要： Proposed is a method for collecting valuable metal from an ITO scrap including a step of collecting tin by subjecting the ITO scrap to electrolysis. Further proposed is a method for collecting valuable metal from an ITO scrap including the steps of providing an ITO electrolytic bath and a tin collecting bath, dissolving the ITO scrap in the electrolytic bath, and thereafter collecting tin in the tin collecting bath. Additionally proposed is a method for collecting valuable metal from an ITO scrap including the steps of dissolving the ITO scrap by subjecting it to electrolysis as an anode in electrolyte, precipitating only tin contained in the solution as tin itself or a substance containing tin, extracting the precipitate, placing it in a collecting bath, re-dissolving this to obtain a solution of tin hydroxide, and performing electrolysis or neutralization thereto in order to collect tin. Consequently, provided is a method for efficiently collecting tin from an ITO scrap of an indium-tin oxide (ITO) sputtering target or an ITO scrap such as ITO mill ends arising during the manufacture of such ITO sputtering target.

摘要： A method for separating impurities from a gallium material containing impurities, which comprises providing the gallium material in a liquid state in a container, allowing the coagulation of gallium to proceed gradually from the surface of the inner wall of the container toward center portion thereof, in a manner such that a cylinder formed by a coagulation interface gradually reduces in its diameter, separating a liquid phase remaining in the central portion from a coagulated phase before the coagulation of the whole material in the container and repeating the above-described procedure using the resultant coagulated phase as a gallium material until a desired purity is achieved. The formation of a gallium product having a purity suitable to preparation of a compound semiconductor can be confirmed by determining the concentrations of impurities in a Ga material being separated from the coagulated phase and containing condensed impurities.

摘要： The invention relates to a method of treating a liquid gallium or gallium alloy surface for prolonged use as a liquid mirror. The method of the invention comprises the steps of (a) contacting the surface of liquid gallium or gallium alloy with an aqueous solution of a halogenic acid to cause dissolution of any gallium oxide present on the surface, thereby obtaining an oxide-free liquid gallium or gallium alloy surface covered with a layer of the acid solution; (b) adding to the acid solution an aqueous solution of a surfactant present in an amount to form a single bimolecular layer of surfactant at an interface between the liquid gallium or gallium alloy and water; and (c) allowing a uniform passivating oxide layer to gradually form on the oxide-free liquid gallium or gallium alloy surface, the passivating oxide layer having surface irregularities smaller than 40 nm.

摘要： Scrap containing gallium and arsenic is treated with chlorine gas to form a crude gallium and arsenic chloride mixture. Arsenic chloride and impurities having a lower boiling point than that of arsenic chloride are removed from the mixture by vaporization so that crude gallium chloride may be obtained. The crude gallium chloride is purified by distillation. The purified gallium chloride is electrolyzed to yield metallic gallium. If the scrap has a molar gallium/arsenic ratio exceeding l, arsenic chloride or metallic arsenic or both are added to the scrap before it is treated with chlorine gas.

摘要： Metallic gallium is efficiently produced by electrolysis of a gallium containing alkali metal aluminate solution arising in the Bayer process. This solution is obtained by cooling an alkali metal aluminate solution after the aluminium hydroxide separation step in the Bayer process, optionally in the presence, as a seed, of at least one alkali metal salt containing vanadium and/or phosphorus, or a complex containing the alkali metal salt, to precipitate crystals of impurities containing vanadium and/or phosphorus, and removing the precipitate, the alkali metal aluminate solution being subjected to oxidation treatment either after removal of the precipitate of impurities or before the cooling step following aluminium hydroxide separation.
