摘要： A process for producing a solder product and a copper product from a first lead-tin based metal composition having at least 40% wt of copper and at least 5.0% wt together of tin and lead. The process includes the steps of
partially oxidizing a first liquid bath having the first lead-tin based metal composition, thereby forming a first dilute copper metal composition and a first solder refining slag, followed by separating the slag from the metal composition, and
partially oxidizing a second liquid bath having the first dilute copper metal composition, thereby forming a first high-copper metal composition and a third solder refining slag, followed by separating the third solder refining slag from the first high-copper metal composition,
whereby the solder product is derived from the first solder refining slag.-

摘要： The treating method for a positive electrode for a non-aqueous electrolyte secondary battery is a treating method for a positive electrode for a non-aqueous electrolyte secondary battery which comprises a positive electrode having a foil containing Al and an active material which is a metal composite oxide, the method comprising: conducting a heating treatment for heating the positive electrode (heating step); melting the positive electrode using heat of reaction of the foil and the active material to obtain a molten material (melting step); and separating the molten material into a metal material containing a metal constituting the metal composite oxide and a slag (separating step). By subjecting the positive electrode to heating treatment, a reduction reaction of the positive electrode can be promoted at a low cost.

摘要： The present invention provides an apparatus for preparing a metal based on solar energy thermal reduction. The apparatus includes a solar energy collection and photothermal conversion system and a thermal reduction system. The solar energy collection and photothermal conversion system includes: a solar energy collection device (1), a solar energy concentration device (2), and a solar energy transfer device (3) or a photothermal conversion and transfer device. The thermal reduction system includes: a metal reduction chamber (15), an electric field and/or magnetic field generation device (15-3), and a separation and cooling device (15-4). The solar energy collection and photothermal conversion system transfers sunlight or heat to the metal reduction chamber to decompose a metal oxide, and a product resulted from the decomposition is dissociated under the effect of an electric field/magnetic field, and a liquid metal is obtained upon cooling. The apparatus further includes a waste heat recovery and recycle system. According to the present invention, the metal oxide is heated and decomposed by directly using the solar energy, which improves energy utilization rate, greatly prevents environmental pollution and energy waste, and has a great application prospect.

摘要： The invention discloses improvements and additional uses of thermo-mechanical processes using a rotary kiln for the separation of parts from a device that are held together by various means such as solder, epoxies, glues, and/or any other thermally degradable adhesives or underfills, and which is suitable for material size reduction via thermal decomposition of encapsulant materials such as integrated circuit casings or thermally degradable materials such as carbon-based hydro processing catalysts. The invention includes further sorting the materials according to predetermined size either in-situ or in series using a meshed vibrating table downstream of the rotary kiln. These devices can include, but not limited to, printed circuit boards, catalysts, solar panels, and the like.
