    摘要： The invention relates to recovery of tin-lead solder from electronic printed circuit board scrap. The scrap is placed in a liquid-permeable and/or gas-permeable container, which is placed in a liquid or gaseous heat-transfer medium heated to or above the melting temperature of the tin-lead solder. After the tin-lead solder is melted, the heat-transfer medium is removed from the container, then, by means of rotation of the container, the melted tin-lead solder and the remains of the heat-transfer medium are removed from the container. The device comprises a hollow container, which is mounted so as to be capable of rotation and is designed in the form of a body of revolution, and is liquid-permeable and/or gas-permeable in a radial direction from the axis of rotation. The container can be designed in the form of a drum, which can be vertically displaced and has perforated side walls.

    摘要： The disclosure relates to a method for sorting a collection of bodies including cemented carbide bodies and non-cemented carbide bodies. A melt having one or more of bismuth, tin and lead and having a density in the range of 7.0-12.0 g/cm3 is provided. The collection is subjected to a sorting process based on density difference by providing the collection in the melt and allowing the bodies to be sorted into a first group at a top surface of the melt and a second group at a bottom of the melt. The first group includes non-cemented carbide bodies having a density lower than the density of the melt and the second group includes cemented carbide bodies having a density higher than the density of the melt. The present disclosure also relates to a method for recycling of cemented carbides comprising the sorting method and recycling of the second group.

    摘要： The present invention relates to a method of concentrating and recovering precious metals from waste mobile phone PCBs and spent automotive catalysts using waste nonferrous slag, in which precious metals such as gold, silver, platinum, palladium or rhodium can be concentrated and recovered by simultaneously treating different industrial wastes, including waste nonferrous slag, waste mobile phone PCBs and spent automotive catalysts, and industrial waste can be recycled as resources. According to the present invention, it is possible to maximize the utilization ratio of precious metal resources that totally depend on the import in terms of the domestic situation of a poor-natural resources country. In addition, the industrial waste can widely be utilized for the recovery of precious metals in the fields of household appliance recycling and electronic part manufacture, and the recycling of industrial by-products discharged in the field of non-ferrous refinery.

    摘要： Proposed is a method for separating dross in a soldering process for a printed circuit board using a tin bath containing liquid tin. The method includes collecting dross produced during the soldering process; grinding the dross to tin ash in the tin bath for allowing a portion of tin contained in the tin ash to be melted again to join the liquid tin; and scooping up and recycling the tin ash not melted in the tin liquid. The method precludes a waste of tin resources and high manufacturing costs which might otherwise arise from directly scooping up dross of high tin content.

    摘要： Proposed is a method for collecting valuable metal from an ITO scrap in which a mixture of indium hydroxide and tin hydroxide or metastannic acid is collected by subjecting the ITO scrap to electrolysis in pH-adjusted electrolyte, and roasting this mixture as needed to collect the result as a mixture of indium oxide and tin oxide. This method enables the efficient collection of indium hydroxide and tin hydroxide or metastannic acid, or indium oxide and tin oxide 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.

    摘要： When dross is removed from a molten-solder reservoir, a substantial amount of molten solder is often removed with the dross. This molten solder can be separated from the dross and returned to reservoir via a conduit for reuse. Additionally, a skimmer for removing the dross from the reservoir includes a skimming plate pivotally attached to a displaceable structure; a stop is provided to restrict the degree to which the skimming plate can pivot so that the skimming plate will not pivot more than 90° from vertical to enable the skimming plate to dig into the dross and collect dross when the displaceable structure is displaced toward on outlet of the reservoir. Further still, the displaceable structure of the skimmer can be controlled via a computer control system storing software code instructions for a motor to extend and retract the displaceable structure such that the skimming plate extends to a position further from the outlet port of the reservoir with each displacement cycle.
