  • Publication number: 20230033441
    Abstract: This invention patent application addresses a system for the detection and quantification of mineralogical species via x-ray diffraction (XRD) of the concentrate of dry copper before it is injected into a converter or melting furnace. Specifically, it addresses a device that performs a mineralogical analysis, in line and in real time, of the concentrate of copper in the bath smelting furnace via x-ray diffraction (XRD), which allows for control over the ideal mixture for the optimal process for copper sulfide (Cu2S)-white metal, iron sulfide (FeS)-Slag and pyritic sulfur (S2)-temperature.

  • Publication number: 20230003569
    Abstract: This application addresses a wireless system for the determination of the height of liquid or molten metal levels containing metal, shaft, matte or slag in smelting furnace. Specifically, it addresses a wireless system that allows, without the presence of cables, the sending and receiving of a signal outside of the smelting furnace, in order to determine, on-line, the height of the phases, including the height of the slag-matte interface and the total level of the bath.

  • Publication number: 20220412656
    Abstract: This invention patent application addresses a thermal launder that allows the transport of white metal (WM) or other molten material to a converter or furnace or from these to a transfer pot while keeping it molten, with a viscosity that allows the material to continue flowing en route.
