According to the method, the microplastic particles are precipitated in the water system without the use of an additional coagulant, whereby the effect of coagulants on the subsequently recovered microplastic aggregates may be ruled out. In addition, the process configuration is simple because the aggregates can be separated from the supernatant without using any additional treatment process.

A method for recovering active metals of a lithium secondary battery may supply a cathode active material mixture to a fluidized bed reactor including a reactor body. A reaction gas may be introduced from a lower portion of the fluidized bed reactor to form a fluidized bed including a preliminary precursor mixture within the reactor body. The fluidized bed portion that has entered the upper portion of the fluidized bed reactor may be cooled to descend it into the reactor body, and then a lithium precursor may be recovered from the preliminary precursor mixture. Accordingly, a terminal velocity of the preliminary precursor is reduced, such that even if the particle size of the preliminary precursor is fine, loss due to scattering may be prevented.
