  • Ile ìdánilẹ́kọ̀ọ́ bọ́lù The ball mill is a rotating cylindrical vessel partially filled with steel balls (typically 20–50 mm in diameter). As the mill rotates, the balls cascade and impact the ore, reducing it to a slurry with particles <75 μm. This comminution process is critical for liberating manganese minerals embedded within gangue particles, with liberation efficiency directly influencing downstream recovery.
  • Classifier Iru Fi: Post-grinding, the slurry is directed to a spiral classifier, which separates particles based on settling velocity. Coarse particles (>75 μm) are returned to the ball mill for regrinding, while fine particles (<75 μm) proceed to beneficiation. This closed circuit minimizes overgrinding, reduces energy consumption, and ensures the ore is ground to the optimal fineness for mineral separation.

  • Iyanrin Alailowaya Ihu Magnetic (HGMS): Manganese minerals (e.g., manganite, psilomelane) often exhibit paramagnetic or ferromagnetic properties. The HGMS generates a high-intensity magnetic field (>1.5 T) using a matrix of ferromagnetic wires, attracting and separating magnetic manganese minerals from non-magnetic gangue (e.g., quartz, feldspar). This process can upgrade manganese grade from 20–30% to 45–55%, depending on ore type.
  • Shaking Table (Ìyànsun Gíráfí ): For manganese ores with significant density differences (manganese minerals ~4.5–5.0 g/cm³ vs. gangue ~2.6–3.0 g/cm³), shaking tables are employed. These tables utilize differential motion and water flow to separate particles by density, concentrating manganese minerals in the concentrate zone while rejecting gangue as tailings. This step is particularly effective for recovering fine-grained manganese minerals missed by magnetic separation.

  • Sise pọ̀n.: The manganese concentrate slurry is fed into a lamella or circular thickener, where solid particles settle under gravity. Polymer flocculants are often added to accelerate settling, increasing the slurry’s solids content from ~10–20% to ~50–60%. This reduces the volume of material requiring filtration, lowering operational costs.
  • Fọto Ẹgbẹ́: A rotary vacuum filter is used to dewater the thickened concentrate. It employs vacuum pressure to draw water through a filter cloth, producing a filter cake with moisture content
