mini pilot flotation plant

A mini pilot flotation plant is a small-scale version of an industrial flotation system used for mineral processing research, testing, and optimization. These plants are designed to simulate full-scale flotation operations while requiring minimal sample quantities (typically a few kilograms to hundreds of kilograms per hour). They help in evaluating ore performance, reagent selection, and process parameters before scaling up.

Key Features of a Mini Pilot Flotation Plant:

1. Modular Design – Compact and portable units that can be transported to mine sites or operated in laboratories.
2. Scalability – Results can be extrapolated to predict industrial-scale performance.
3. Flexibility – Adjustable parameters (airflow, agitation speed, reagent dosing) for different ore types.
4. Automation & Control – Often equipped with sensors and control systems for precise operation.
5. Low Feed Requirement – Works with small ore samples (unlike full pilot plants that need tons of material).

Typical Components:

• Feed Preparation Unit (crushing, grinding, slurry conditioning)
• Flotation Cells (mechanical or pneumatic, often 1–10 L capacity)
• Pumps & Mixers
• Reagent Dosing System
• Control Panel & Data Acquisition System
• Froth Collection & Tailings Handling



Applications:

✔ Ore characterization
✔ Process optimization
✔ Reagent screening
✔ Circuit design validation
✔ Training purposes

Advantages Over Lab-Scale Tests:

• Better mimics continuous industrial conditions than batch tests.
• Provides more reliable scale-up data.
• Reduces risks before investing in large-scale plants.



Examples of Mini Flotation Pilot Systems:

• Outotec (Metso) MiniPilot
• FLSmidth’s Rapid Oxidative Leach (ROL) + Flotation Systems
• Bench-scale Denver or Wemco cells adapted for continuous operation
