    摘要： The current invention pertains to methods for chemical modification of constituents of liquid stream containing organic or inorganic constituents. The methods include steps of: providing at least one reactor device having one or more reaction chambers that include at least one first boundary substance and containing liquid streams; generating at least one second boundary substance from the at least one first boundary substance and the at least one organic or inorganic constituent of the at least one liquid stream; dissolving the at least one second boundary substance in at least one another liquid stream and generating a solution of greater dissolved second boundary substance concentration than the respective constituent initial occurrence in the at least one liquid stream; regenerating the at least one first boundary substance for subsequent generation of the at least one second boundary substance.

    摘要： A method of recovering metals from electronic waste comprises providing a powder comprising electronic waste in at least a first reactor and a second reactor and providing an electrolyte comprising at least ferric ions in an electrochemical cell in fluid communication with the first reactor and the second reactor. The method further includes contacting the powders within the first reactor and the second reactor with the electrolyte to dissolve at least one base metal from each reactor into the electrolyte and reduce at least some of the ferric ions to ferrous ions. The ferrous ions are oxidized at an anode of the electrochemical cell to regenerate the ferric ions. The powder within the second reactor comprises a higher weight percent of the at least one base metal than the powder in the first reactor. Additional methods of recovering metals from electronic waste are also described, as well as an apparatus of recovering metals from electronic waste.

    摘要： Disclosed is tin characterized in that a sample of the tin after melting and casting has an α dose of less than 0.0005 cph/cm2. Since recent semiconductor devices are highly densified and of high capacity, there is an increasing risk of soft errors caused by the influence of α rays emitted from materials in the vicinity of semiconductor chips. In particular, there are strong demands for high purification of solder materials and tin for use in the vicinity of semiconductor devices, and demands for materials with lower α rays. Accordingly, an object of the present invention is to clarify the phenomenon of the generation of α rays in tin and tin alloys, and to obtain high-purity tin, in which the α dose has been reduced, suitable for the required materials, as well as a method for producing the same.

    摘要： Proposed is a method for collecting valuable metal from an ITO scrap including the steps of subjecting the ITO scrap to electrolysis and collecting the result as indium-tin alloy. Additionally provided is a method for collecting valuable metal from an ITO scrap including the steps of providing an ITO electrolytic bath and an indium-tin alloy collecting bath, dissolving the ITO in the electrolytic bath, and thereafter collecting indium-tin alloy in the indium-tin alloy collecting bath. These methods enable the efficient collection of indium-tin alloy from an ITO scrap of an indium-tin oxide (ITO) sputtering target or an ITO scrap such as ITO mill ends arisen during the manufacture of such ITO sputtering target.
