Abstract: The invention concerns a process for the separation of cobalt from lithium present in a charge comprising lithium-ion batteries or related products, comprising the steps of: smelting the charge using a bath furnace equipped with a submerged air-fed plasma torch for injecting plasma gas into the melt; defining and maintaining a bath redox potential where cobalt is reduced to the metallic state and reporting to an alloy phase, and whereby lithium is oxidized as Li 2 O and reporting to the slag phase; decanting and separating the phases. It is characterized in that the reduction and oxidizing steps are performed simultaneously. A suitably low cobalt concentration is obtained in the slag.

Abstract: The present invention concerns a process for the recovery of metals and of heat from spent rechargeable batteries, in particular from spent Li-ion batteries containing relatively low amounts of cobalt. It has in particular been found that such cobalt-depleted Li-ion batteries can be processed on a copper smelter by: -feeding a useful charge and slag formers to the smelter; -adding heating and reducing agents; whereby at least part of the heating and/or reducing agents is replaced by Li-ion batteries containing one or more of metallic Fe, metallic Al, and carbon. Using spent LFP or LMO batteries as a feed on the Cu smelter, the production rate of Cu blister isincreased,while the energy consumption from fossil sources is decreased.

Abstract: The present invention concerns the recovery of cobalt from cobalt-bearing materials, in particular from cobalt-bearing lithium-ion secondary batteries, from the spent batteries, or from their scrap. A process is divulged for the recovery of cobalt from cobalt-bearing materials, comprising the steps of: providing a converter furnace,charging slag formers and one or more of copper matte, copper-nickel matte, and impure alloy into the furnace, and injecting an oxidizing gas so as to smelt the charge in oxidizing conditions, thereby obtaining a molten bath comprising a crude metal phase, and a cobalt-bearing slag,and separating the crude metal from the cobalt-bearing slag, characterized in that the cobalt-bearing materials are charged into the furnace. This process is particularly suitable for recycling cobalt-bearing lithium-ion secondary batteries. Cobalt is concentrated in a limited amount of converter slag, fromwhich it can economically be retrieved, together with other elements such as copper and/or nickel.
