  • Procedure for extraction of brass, zinc oxide and copper

    The method of extraction of brass, zinc oxide and copper oxide from the slag brass foundry carried out according to the scheme shown in the drawing, where the furnace 1, the original slag 2, the crusher 3, crushed slag 4, magnetic separator 5, ferrous metals 6, the container 7 for ferrous scrap, slag 8 without ferrous metals, vibrating screen 9, brass 10 splash, the drive 11 of the treated

  • Leaching and recovery of zinc and copper from brass slag

    The analysis of the residue (slag sample after leaching process) indicated that it contained only quartz (SiO 2) as the main constituent. 4. Conclusions. Leaching of brass slag to recover zinc and copper in sulfuric acid solutions was studied. It was found that the zinc extraction was fast and increased with sulfuric acid concentration.

    2020-06-07· Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 °C, 1,650 to 1,720 °F, depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass
