Key Stages of the Manganese Ore Beneficiation Production Line

1. Igbese Ikọlu

• Feeder:Ẹrọ titẹ tabi apron feeder ni a nlo lati ṣe iwọn ore raw sinu ẹkọ ikọlu. O rii daju pe o jẹ ṣiṣan, iṣakoso iwọn, ti o yago fun ikolu awọn crushers ati ṣiṣe iduroṣinṣin ilana.
• PE Jaw Crusher (Ipin Ija):Bi ipele akọkọ ti idinku iwọn, PE jaw crusher n lo agbara compressive nipasẹ awọn pẹpẹ afọwọkọ ti n dapọ lati dinku awọn itọsẹ خام (igbagbogbo
• Cone Crusher (Ija Keji):Ẹrọ igun n ṣiṣẹ pẹlu a mantẹ ti n yika inu concave ti o duro, nlo awọn agbara compressive ati shearing mejeeji lati dinku awọn ore si
• Àtẹ̀wéwé Ẹ̀fọ̀: A multi-deck vibrating screen classifies the crushed ore. Oversized particles (>25 mm) are recirculated to the cone crusher (forming a closed circuit), while undersized particles pass to the small size ore bin for grinding. This configuration maximizes crushing efficiency and ensures consistent feed size for the mill.

2. Grinding and Classification Section

Grinding and classification work synergistically to liberate manganese minerals from gangue at the microscale. This section employs a closed-circuit grinding circuit to balance fineness and energy efficiency.

• Small Size Ore Bin & Feeder: Awọn ohun alumọni ti a fọ ni a tọju ninu agbada iṣan ati pe a n feed sinu mill nipasẹ ẹrẹkẹ tabi ẹrọ gbigbe, n ṣetọju ṣiṣan ohun elo ti o wa ni iduroṣinṣin. Eyi ṣe idiwọ starvation mill tabi overload, n ṣatunṣe kinetics grinding.

• High Gradient Magnetic Separator (HGMS):Awọn ọlọrọ manganese (e.g., manganite, psilomelane) nigbagbogbo n fihan awọn ohun-ini paramagnetic tabi ferromagnetic. HGMS n ṣẹda aaye ọlọrọ magnetik ti o ga (>1.5 T) nipa lilo matrix ti awọn okun ferromagnetic, n fa ati ya awọn ọlọrọ manganese to magnetik kuro ninu awọn ohun elo ti ko ni magnetik (e.g., quartz, feldspar). Ilana yii le mu iwọn manganese u lati 20–30% si 45–55%, da lori iru irin.
• Shaking Table (Gravity Separation): 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.

• Thickener: 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.
• Vacuum Filter: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
• Concentrate Silo:Concentrate manganese ti a ko omi ni a tọju ninu silo ti o ni abẹ ẹyẹ, eyi ti o mu agbara gbigbe jade ati ki o ṣe idiwọ ikojọpọ ohun elo. Silo naa jẹ ki ipese ti o tẹsiwaju ti concentrate fun ikojọpọ tabi awọn ilana isalẹ (e.g., pelletizing).

The manganese ore beneficiation production line illustrated offers several advantages:

• Integration of Multiple Technologies:By combining crushing, grinding, magnetic separation, and gravity separation, the line can handle various manganese ore types, from oxidic to siliceous ores.
• Energy and Resource Efficiency:Closed-circuit crushing and grinding, along with water recycling, reduce energy and water consumption, making the process economically and environmentally sustainable.
• Flexibility and Scalability:The modular design of equipment allows for adjustments based on ore characteristics and production demands, enabling both small-scale and large-scale operations.
