  • Publication number: 20230369667
    Abstract: The present invention lies in the field of pyrometallurgy and discloses a process and a slag suitable for the recovery of Ni and Co from Li-ion batteries or their waste, particularly from Black Mass. The slag composition is defined according to: 25% < MnO < 70%; Al2O3 + 0.5 MnO < 45% SiO2 > 5%; Li2O > 1%; MnO + Li2O + Al2O3 + CaO + SiO2 + FeO + MgO + P2O5 > 90%; and, wherein (CaO + 2 Li2O + 0.4 MnO) / SiO2 ? 2.0. This composition is particularly adapted to limit or avoid the wear or corrosion of furnaces lined with magnesia-bearing refractory bricks.
