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.

A disclosed dilute copper metal composition has 57-85% wt Cu, ≥3.0% wt Ni, ≤0.8% wt Fe, 7-25% wt Sn and 3-15% wt Pb. A process includes partially b) oxidizing a black copper composition to obtain a first copper refining slag and a first enriched copper metal. The process further includes oxidizing h) the first enriched copper metal to obtain a second copper refining slag, whereby at least 37.0% wt of the amount of tin and lead processed through steps b) and/or h) is retrieved in the first and second copper refining slags together, partially reducing c) the first copper refining slag to form a first lead-tin based metal composition and a first spent slag, adding the second copper refining slag to the first lead-tin based metal composition thereby forming a first liquid bath, partially oxidizing d) the first liquid bath, thereby obtaining the dilute copper metal composition.

The present invention relates to the field of alloy-smelting facilities, and provides an aluminum-based ultra-thin launder. The launder has a body with a wall thickness of 12 mm to 25 mm. The body has a segmented structure, including a part of alloy in, a first launder, a second launder and a part of alloy out that are connected in sequence. The body of the launder provided in the present invention is lighter and thinner. The cost of production and use is reduced due to the significantly-decreased wall thickness and weight. The connection mode for components of the body is changed, which is beneficial to the replacement, and fundamentally lowers the risk of a repair material contaminating melted alloy.

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.
