This invention belongs to the field of mineral flotation technology, specifically relating to a forced slurry conditioning-eddy current mineralization-static separation mineral flotation system and method. It includes a slurry conditioning cylinder, a separation chamber, and a mineralization cylinder connected in sequence. The slurry conditioning cylinder contains a slurry conditioning pipeline; the separation chamber contains raw ore processing pipelines and middlings processing pipelines; and the mineralization cylinder contains an eddy current mineralization pipeline. The slurry conditioning pipeline, raw ore processing pipeline, eddy current mineralization pipeline, and middlings processing pipeline are connected sequentially. After minerals and flotation reagents are conditioned in the slurry conditioning cylinder to obtain raw ore slurry, it passes through the separation chamber to obtain middlings ore slurry, which then enters the eddy current mineralization pipeline. The middlings ore slurry returns to the separation chamber and enters the middlings processing pipeline for flotation separation. Finally, concentrate is collected at the top of the separation chamber. The mineral flow path designed in this invention enables efficient collisions between minerals of different particle sizes and slurry conditioning reagents, as well as between minerals and air bubbles, achieving effective flotation recovery.
