  • Patent number: 12209028
    Abstract: A process recovers metals from a black mass. The process includes the following steps in the following order: step (a) providing the black mass, which comprises Li; step (b) adding water to the black mass and creating a suspension of the black mass in the water; step (c) dosing ozone as an oxidant to the suspension while stirring the suspension; and step (d) filtering and separating a filtrate containing LiOH dissolved in water from a Li depleted residue of the black mass. In step (c), the suspension is stirred with a shear rate greater than 11000 s?1 within the suspension.

  • Publication number: 20240399446
    Abstract: A casting mould produces copper anodes for producing high-purity copper. The casting mould has: a first flat cavity, which is delimited by two lateral surfaces aligned in parallel with each other; two second cavities, which are fluidically connected to the first flat cavity, are arranged on different corners on a peripheral side of the first flat cavity, and extend laterally outwardly away from the first flat cavity; and a core. The core is provided centrally in a respective second cavity of the second cavities. The core sub-divides the respective second cavity at least partially into a closed annular shape in the peripheral direction.

  • Publication number: 20240278313
    Abstract: The invention relates to a casting mould (7) for producing copper anodes (1) for producing high-purity copper, having—a first, extensive cavity (8), which is delimited by two side faces oriented parallel to one another, and—two second cavities (9) which are fluidically connected to the first cavity, are arranged on a peripheral side of the first cavity (8) at different corners and extend laterally outwardly away from the first cavity (9), characterized in that—a core (20) is provided centrally in each of the second cavities (9), said core (20) subdividing each second cavity (9) at least partially to form a circumferentially closed ring shape.
