Devices, systems, and their methods of use, for sorting or separating magnetic particles are provided. A magnetic source is disposed adjacent a flow path and exerts a magnetic field on magnetic particles in order to separate particles.

The invention concerns a method for separating at least one rare earth element from a solution containing said at least one rare earth element and optionally at least one further magnetic element, the method comprising the following steps a) applying to the solution a non-uniform magnetic field, whereby creating within the solution at least one first zone and at least one second zone having a different magnetic field value, the application of the non-uniform magnetic field value inducing concentrating said at least one rare earth element in the first zone and concentrating said optional at least one further magnetic element in the second zone, b) increasing the pH of the solution in the first zone, to precipitate said at least one rare earth element, or in the second zone to precipitate said optional at least one further magnetic element, and c) recovering the precipitate.

Systems and methods are provided for separating mixed metals from one another out of batteries (e.g., lithium ion batteries (LIBs)). Magnetic field gradients can be used to separate mixed metals from one another, and the products of the separation (e.g., lithium (Li), nickel (Ni), manganese (Mn), and/or cobalt (Co)) can be used again in other manufacturing processes, such as to manufacture new LIBs.

Apparatus and associated methods relate to separate ferromagnetic impurities from bulk battery materials. In an illustrative example, a ferromagnetic impurity separation system (FISS) may receive a sample vessel including an enclosed sample of bulk battery materials. The FISS, for example, may include a variable magnetic flux generator (e.g., an electromagnet) disposed at a position separated from the sample vessel. The FISS may also include an agitation unit having a translational motor and a rotational motor configured to rotate the sample vessel about a central axis, and to translate a position of the central axis of the sample vessel. For example, in an operation mode, the variable magnetic flux generator and the agitation unit may apply a predetermined magnetic flux, a predetermined angular velocity and a predetermined velocity to the sample vessel. Various embodiments may advantageously separate ferromagnetic impurities from the enclosed sample concisely without contaminating the sample.
