In mining operations, thickener plays a crucial role in the dewatering process, separating liquids from solids to recover water and concentrate slurries. Here are key aspects of thickeners used in mining plants:
Types of Thickeners
1. Conventional Thickeners
– Use gravity sedimentation with a raking mechanism.
– Suitable for large volumes of slurry with moderate settling rates.
2. High-Rate Thickeners
– Incorporate flocculants (polymers) to accelerate settling.
– Higher throughput than conventional thickeners.
3. Paste Thickeners
– Produce thicker underflow (higher solids content).
– Used for tailings disposal or backfill preparation. .jpg)
4. Deep Cone Thickeners
– Designed for ultra-high-density slurries (e.g., coal, iron ore).
Key Components
- Tank & Feed Well: Distributes slurry evenly for uniform settling.
- Rake Mechanism: Moves settled solids toward the discharge point.
- Flocculant Dosing System: Enhances particle aggregation for faster settling.
- Underflow Pump: Removes thickened slurry for further processing/disposal.
- Tailings dewatering (water recovery & reduced storage footprint).
- Concentrate thickening before filtration/drying.
- Clarification of process water for reuse.

Selection Factors
✔️ Particle size & slurry density
✔️ Required underflow density (% solids)
✔️ Chemical additives (flocculants) compatibility
✔️ Space constraints & operational costs
