Outotec® FrothMaster 2

Outotec® FrothMaster 2 is a tool for real-time froth surface analysis. The FrothMaster™ system measures several essential properties of froth appearance including froth speed, bubble size, froth stability and froth color and provides statistical data related to these variables. The measured froth properties, together with on-stream analyzer assays, enable expert control of the flotation circuit.bIn addition, using advanced web server technology, FrothMaster™ provides the option for convenient monitoring of froth characteristics anywhere in the world.

A typical FrothMaster™ installation has several froth imagers mounted on top of flotation machines. The imagers are networked through intelligent connection boxes to a FrothManager station, which acts as a gateway to the plant automation system and office network. The FrothManager station can run optional ACT expert system applications for flotation circuit froth recovery, mass balancing and adaptive cell level controls.

The FrothMaster™ 2 imager module FIS 6210 consists of a high-resolution color camera, controlled light and optional sunshade. The imager module is designed for flotation plant environment and is IP65 rated.

Vision-based flotation control

Flotation plant operators use visual information of froth appearance for operative decisions. Froth camera system is a tool to overcome subjective factors and provide consistent information 24 hours a day for process control and optimization.
