    摘要: 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.

    摘要: A system for generating mechanical waves for use in smelting and conversion processes that occur in furnaces and converters for a higher production of refined metals, consisting in an electrical signal generator, transducers that convert said electrical signals in mechanical waves placed on the outer end of air blowing tuyeres and a coupling means between said system and the shell of the converter. The air blowing tuyeres are placed forming an 180° angle in the direction of the airflow entrance, while the transducers are placed transversally to the air blowing tuyeres so as to apply mechanical waves that travel in a transversal direction with the air flow into the converter or pyrometallurgical furnace. The field of mechanical waves allows a higher efficiency in the oxygen reactions within the metal bath and slag, increasing the kinetics of chemical reactions, allowing a quicker homogenization of the metal bath and reducing notoriously the copper trapped mechanically by the slag, all this leading to a higher production of metal.

    摘要: The invention relates to a method for adjusting the flow velocity of reaction gas and the dispersion air of pulverous solids when feeding reaction gas and finely divided solids to the reaction shaft (6) of a suspension smelting furnace for creating a controlled and adjustable suspension. Reaction gas (8) is fed into the furnace from around a finely divided solid material flow (5), so that said solids are distributed with an orientation towards the reaction gas by means of dispersion air. The flow velocity and discharge direction of the reaction gas to the reaction shaft are adjusted steplessly by means of a specially shaped adjusting member (10) moving vertically in the reaction gas channel (13) and by means of a specially shaped cooling block (12) surrounding the reaction gas channel (13) and located on the arch of the reaction shaft. The velocity of the reaction gas is adjusted to be suitable, irrespective of the desired gas quantity, in the discharge orifice (14) located at the bottom edge of the reaction shaft arch (11), and from said orifice the gas is discharged into the reaction shaft (6) and forms there a suspension with the pulverous material, and the dispersion air needed for dispersing said material is adjusted according to the supply of the pulverous material. The invention also relates to a multiadjustable burner for realizing the method.

    摘要: A non-ferrous matte conversion process is disclosed in which molten non-ferrous matte, essentially nickel and/or copper sulfide and iron sulfide, is provided in a suitable vessel, such as a modified Pierce-Smith converter. The bath is stirred from below with a non-reactive sparging gas, such as nitrogen, and surfaceblown from above with an oxygen-containing gas. A flux is added to the melt to raise a fluid slag. In addition, cold crushed matte is added to the bath. The cold matte acts to maintain the temperature of the bath, so as to prevent overheating which can damage the converter lining. The matte addition also serves as a source for additional converter feed. As the reaction progresses, the slag layer is periodically skimmed, and additions of flux and cold matte are made when necessary. When it is no longer possible to raise a slag, a non-ferrous sulfide matte is obtained having a greatly reduced iron content.
