摘要： A method of recycling useful metals is provided. The method enables useful metals including indium, zinc, yttrium, europium, lanthanum, terbium, gadolinium, antimony, lead, copper, tin, and silver to be recovered from wastes, such as wasted flat panel displays, and recycled economical with small energy consumption. The method of recycling useful metals includes: a step in which wastes comprising various flat panel displays, e.g., liquid-crystal display panels, are crushed/powdered; a step in which the resultant particles are dissolved in an aqueous hydrofluoric acid solution; and a step in which various metal oxides and various metal fluorides which remain undissolved are filtered off and the aqueous hydrofluoric acid solution containing various metal ions is electrolyzed to deposit and recover metals for transparent-electrode oxides, such as indium and zinc, and other useful metals.

摘要： Sulphidic zinc concentrate usually also includes small amounts of rare metals such as indium and gallium. If the content of these metals in the raw material is sufficiently high, their recovery may be economically worthwhile. In the method according to the invention the recovery of indium and other desirable rare metals takes place in a zinc leaching process, in which at least part of the sulphidic concentrate is leached directly without roasting.

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.
