Nika da kuma rarrabawa suna aiki tare don sakin ma'adinai na manganese daga gangue a matakin microscale. Wannan sashe yana amfani da hanyar nika mai rufaffiyar hanya domin daidaita launin da kuma ingancin enerji.

  • Size Ore Bin & Feeder: Ore ɗin da aka yayyafa ana adana shi a cikin akwati mai tsinkaye kuma ana shayar da shi cikin mill ta hanyar ƙwayar ko bel, yana tabbatar da cewa zai iya gudana akai-akai. Wannan yana hana yunwar mill ko cunkoson kayan, yana inganta yanayin niƙa.
  • Mill Ball: 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.
  • Spiral Classifier: 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.

3. Sashen Amfani

Wannan mataki yana amfani da haɗin gwiwar raba magneti da raba nauyi don mai da hankali ga ma'adanai na manganese, yana amfani da halayen su (magnetism, ƙudɗi) dangane da gangue.

  • Filin Tantancewa: Wannan shahararren ragar tantancewa ta amfani da zuwa ƙarfin sauri tana cire manyan datti ko ƙananan kwayoyin daga ruwan ƙasa. Wannan matakin yana tabbatar da cewa abincin da ke zuwa ga mai raba yana da daidaiton girman kwayoyin, yana ƙara ingancin raba.
  • High Gradient Magnetic Separator (HGMS): Mai Raba Magnet na Babban Hanya 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.
  • Teburin Yi Nauyi (Raba Nauyi): 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.

4. Rukunin Cire Ruwa da Sarrafa Samfur

Wannan mataki na karshe yana sarrafa slurry na jan karafa zuwa samfurin ruwa mai ƙananan danshi wanda ya dace da ajiya, sufuri, ko ƙarin sarrafawa.

  • Mai kauri: 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.
  • Fitrin Vacuum: 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
  • Silo na Haɓaka Concentrate ɗin manganese da aka cire ruwa ana adana shi a cikin silo mai ƙasan cone, wanda ke sauƙaƙe fitarwa kuma yana hana taruwa na kayan. Silo na tabbatar da ci gaba da samun concentrate don ɗora ko hanyoyin ƙasa (misali, pelletizing).

The manganese ore beneficiation production line represents a comprehensive and efficient approach to upgrading manganese ore. Each stage—crushing, grinding, classification, beneficiation, and dewatering—plays a vital role in ensuring high manganese recovery and concentrate grade. By leveraging advanced equipment and integrated process design, this production line meets the industry’s need for sustainable and cost-effective manganese ore beneficiation, supporting the global demand for this essential mineral.
