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： A disclosed process produces at least one concentrated copper product together with at least one crude solder product, starting from a black copper composition with at least 50% of copper together with at least 1.0% wt of tin and at least 1.0% wt of lead The process includes the step of partially oxidizing the black copper thereby forming a first copper refining slag, followed by partially reducing the first copper refining slag to form a first lead-tin based metal composition and a first spent slag. The total feed to the reducing step includes an amount of copper that is at least 1.5 times as high as the sum of the amounts of Sn plus Pb present, and the first spent slag includes at most 20% wt total of copper, tin and lead together.

摘要： A dilute copper metal composition includes 57-85% wt Cu, ≥3.0% wt Ni, ≤0.8% wt Fe, 7-25% wt Sn and 3-15% wt Pb. A process includes the steps of partially oxidizing a black copper composition to obtain a first copper refining slag and a first enriched copper metal, partially oxidizing 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 is retrieved in the first and second copper refining slags together; and partially reducing the first copper refining slag to form a first lead-tin based metal composition and a first spent slag. The process further includes the steps of adding the second copper refining slag to the first lead-tin based metal composition, thereby forming a first liquid bath; and partially oxidizing the first liquid bath, thereby obtaining the dilute copper metal composition.

摘要： A process for the production of a crude solder composition includes the provision of a first solder refining slag that includes tin and/or lead. The process further includes the steps of partially reducing the first solder refining slag, thereby forming a crude solder metal composition and a second solder refining slag, followed by separating the second solder refining slag from the crude solder metal composition, and partially reducing the second solder refining slag, thereby forming a second lead-tin based metal composition and a second spent slag followed by separating the second spent slag from the second lead-tin based metal composition A copper containing fresh feed is added to step (ii), preferably before reducing the second solder refining slag.

摘要： A process for a producing crude solder product and a copper product includes the steps of providing a black copper comprising >=50% wt of copper together with >=1.0% wt of tin and/or >=1.0% wt of lead, and refining a first portion of the black copper to obtain a refined copper product together with at least one copper refining slag. The process further includes the steps of recovering a first crude solder product from the copper refining slag, thereby forming a solder refining slag in equilibrium with the first crude solder product, and contacting a different portion of the black copper with the solder refining slag thereby forming a spent slag and a lead-tin based metal, followed by separating the spent slag from the lead-tin based metal.
