Key Stages of the Manganese Ore Beneficiation Production Line

1. Crushing Section

The crushing stage is pivotal for reducing raw manganese ore to a particle size that enables efficient mineral liberation in subsequent grinding. This section employs a closed-circuit crushing circuit to achieve uniform particle size distribution.

  • Feeder:A vibrating or apron feeder is used to meter the raw ore into the crushing circuit. It ensures a steady, controlled feed rate, preventing overloading of crushers and maintaining process stability.
  • PE Jaw Crusher (Primary Crushing):As the first stage of size reduction, the PE jaw crusher utilizes compressive force via reciprocating jaw plates to reduce raw ore (typically
  • cone crusher (secondary crushing): The cone crusher operates with a rotating mantle within a stationary concave, applying both compressive and shearing forces to further reduce the ore to
  • ເຄື່ອງກອງຮອຍ: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.

  • 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.

4. Dewatering and Product Handling Section

This final stage processes the manganese concentrate slurry into a low-moisture product suitable for storage, transport, or further processing.

  • ເຄື່ອງປຸງແຕ່ງ: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
  • စုစုပေါင်း Silo:The dewatered manganese concentrate is stored in a cone-bottom silo, which facilitates discharge and prevents material buildup. The silo ensures a continuous supply of concentrate for loading or downstream processes (e.g., pelletizing).
