Tahapan Kunci ing Jalur Produksi Benefisiari Bijih Manganese

1. Bagian Patah

Tahap penghancuran iku penting kanggo ngurangi bijih mangan mentah dadi ukuran partikel sing ngidini pembebasan mineral sing efisien ing penggilingan sabanjure. Bagian iki nggunakake sirkuit penghancuran sirkuit tertutup kanggo ngasilake distribusi ukuran partikel sing seragam.

  • Feeder: Pang喔vitra utawa apron feeder digunakake kanggo metering bijih mentah menyang sirkuit penghancur. Iki njamin laju pakan sing stabil lan dikontrol, nyegah overloading penghancur lan njaga stabilitas proses.
  • PE Jaw Crusher in Javanese is "Crusher Jaw". (Penggilingan Awal): Minangka tahap pertama saka pengurangan ukuran, PE jaw crusher nggunakake gaya kompresif liwat pelat rahang bolak-balik kanggo ngurangi bijih mentah (biasane
  • Cone Crusher inggih punika "Panghancur Kerucut." (Penggilingan Sekunder): Cone crusher beroperasi kanthi mantel muter ing njero concave sing mandheg, ngetrapake gaya kompresif lan shearing kanggo luwih ngurangi bijih dadi
  • Layangan Getar: Siji layar geter multi-tahap nggolongaké bijih sing wis dihancurake. Partikel sing luwih gedhe (>25 mm) diputer maneh menyang crusher cone (membentuk sirkuit tertutup), nalika partikel sing luwih cilik dipindhah menyang bak bijih ukuran cilik kanggo digiling. Konfigurasi iki maksimalake efisiensi hancur lan njamin ukuran umpan sing konsisten kanggo pabrik.

2. Bagéan Giling lan Klasifikasi

Penggilingan lan klasifikasi kerja sinergis kanggo nglbur mineral mangan saka gangue ing skala mikro. Bagian iki nggunakake sirkuit penggilingan sirkuit tertutup kanggo nemtokake keseimbangan antara kehalusan lan efisiensi energi.

  • Ukuran Cilik Ore Bin & Feeder: Bijih sing wis dihancurkan disimpen ing surge bin lan dipasok menyang penggilingan liwat feeder sekrup utawa sabuk, njaga aliran material sing konstan. Iki nyegah kekurangan bahan baku ing penggilingan utawa overloading, ngoptimalake kinetika grinding.
  • Giling Bola: Gilingan Bola 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.
  • Klasifikasi Spiral: 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. Bagian Beneficiation

Tahap iki nggunakake kombinasi pemisahan magnetik lan pemisahan gravitasi kanggo nyentrake mineral mangan, nggunakake sifat fisik (magnetisme, densitas) kanthi relatif marang gangue.

  • Saringan Layar: Saringan penyaringan frekuensi tinggi ngilangake kotoran kasar utawa partikel sing ora digiling saka slurry sing digiling. Langkah iki njamin panganan kanggo separator duwe ukuran partikel sing seragam, ningkatake efisiensi pemisahan.
  • Separator Magnetik Gradien Dhuwur (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.
  • (Gravitasi Pisah): 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. Bagian Pengeringan lan Penanganan Produk

Tahap pungkasan iki ngeproses slurry konsentrat mangan dadi produk kelembapan rendah sing cocog kanggo panyimpenan, transportasi, utawa pemrosesan luwih lanjut.

  • Pengental: 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.
  • Filter Vakum: 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
  • Konsentrasi Silo: Koncentrat mangan sing wis dipisahaké banyu disimpen ing silo dhasar con, sing ndhukung pambongkaran lan nyegah akumulasi bahan. Silo iki njamin pasokan konsentrasi sing terus-terusan kanggo muat utawa proses hilir (contone, pelletizing).
  • Pompa Slurry & Sirkulasi Air: Pompa slurry berat mindhah slurry abrasif antarane tahap proses, nalika sistem daur ulang banyu njupuk lan nggunakake maneh banyu saka thickeners, filter, lan tailings. Iki nyuda konsumsi banyu tawar nganti >80%, nggawe proses iki lestari kanggo lingkungan.
