Create high-grade concentrates with FLS column flotation cells

FLS froth cameras provide a clear image and analysis of froth movement over the launder, allowing for improved control of the flotation circuit and further optimizing performance. 

Automatically adjust recovery rate based on an algorithm that works with froth cameras and online sample analysers. 

Column flotation cells are a type of flotation device used in mineral processing to separate valuable material from waste (gangue). They are particularly suited to created high-grade concentrate as the final stage in a flotation circuit. 

Column flotation cells feature a deep, stable froth layer for improved recovery rate, and froth washing to improve the final grade of the product. They also generally require less energy than mechanically agitated cells. 

FLS column flotation cells feature a venturi-style sparging system. Air is sheared into the slurry under dynamic pressure changes, providing high-intensity contacting with the bubbles. This method enhanced collision and attachment rates compared to traditional jet-nozzle spargers, greatly improving fines recovery. 

Cross-sectional area and active volume are critical for selecting the appropriate column size for the application. The cross-sectional area helps determine the carry rate (amount of concentrate flowing over the launders divided by the total cross-sectional area) required for the column to perform correctly. The active volume, combined with the feed rate, is used to determine the size and quantity of flotation cells needed in a circuit to achieve the specified recovery rate.

We offer column flotation cells with cross sectional areas of 0.79m² up to 28.27m² and operating volumes of 2.5m³ up to 472.5m³.
