BSA
Bubble Size Analyzer
The AMS BSA is an in-line bubble analyzer for real-time monitoring of bubble size distribution directly in the flotation cell, enabling process optimization to reach optimal recovery and grade.
BSA – Bubble Size Analyzer
The BSA provides real-time process monitoring in flotation cells. Capturing and analyzing thousands of bubbles per minute. It outputs the Bubble Size Distribution, and more, with results displayed directly at the site’s control system (DCS, SCADA).

BSA – Bubble Analyzer
In flotation, knowing the bubble size distribution is critical for achieving optimal recovery and grade. This factor influences:
- Mineral Recovery: Smaller bubbles increase surface area for particle attachment, improving kinetics.
- Selectivity: Controlled bubble size helps separate valuable minerals from gangue.
- Efficiency: Optimized and stable process conditions reduce power consumption and reagent costs.
Traditionally, this measurement were only available through offline sampling, which is time-consuming and prone to error. Our solution changes that.
Our solution
The AMS Bubble Analyzer (BSA) provides real-time bubble characteristics based on image analysis for flotation cells, delivering continuous in-situ monitoring of:
- Bubble Size Distribution (Feret Mean Diameter)
This data enables operators to improve flotation performance.
Key advantages
- Continuous, Real-Time Measurement: No delays, no sampling errors, making it ideal for advanced control systems.
- Statistically Representative Data: Thousands of bubbles analyzed per minute.
- Robust: Wear-resistant housing for long-term reliability.
- Direct Process Insight: The microscopic lens provides images of the pulp phase for better decision-making.
Powerful software 
The BSA uses process microscopy combined with powerful software to analyze thousands of bubbles every minute. The software is installed on a powerful server (workstation) that runs advanced algorithms in combination with a neural network (AI) to identify bubbles in hundreds of images captured in real-time by an in-situ measuring probe.
Easy installation 
The analyzer’s probe is installed in situ, meaning it is mounted directly on the flotation cell. Installation only requires a T-section with a flange. This approach offers significant advantages over traditional methods, as it is more versatile and provides more representative measurements. It also enables measurements at different points, offering greater flexibility.
Virtually no maintenance 
The maintenance needs are extremely low since the AMS Bubble Analyzer’s (BSA) only wear part is a replaceable probe protection cap. Sample methods need a whole infrastructure for the side stream that compromises the operational expenses (OPEX) and could cause issues with availability and representivity of the readings. As the AMS (powered by SOPAT) technology measures in-situ, it does not require a bypass with additional parts such as a sampler, pump, etc., which are sensitive to wear and to the mining environment, making the OPEX for the BSA significantly lower.
