Dynamic Modeling and Real-Time Monitoring of Froth Flotation

A dynamic fundamental model was developed linking processes from the microscopic scale to the equipment scale for batch froth flotation. State estimation, fault detection, and disturbance identification were implemented using the extended Kalman filter (EKF), which reconciles real-time measurements with dynamic models. The online measurements for the EKF were obtained through image analysis of ...

Explaining the Process of Froth Flotation

These collect in a froth heavily laden with sulphide particles. The gangue particles are not brought up by the bubbles, but remain in the mass of the pulp. This is the so-called froth flotation.

Eliminate Flotation Bottlenecks | E & MJ

Traditionally, mechanical flotation design has focused on the pulp zone or residence time, with little emphasis on the mineral’s froth phase. How it performs in the froth is critical—if the mineral doesn’t manage to travel up through the froth from the pulp and then from the froth surface to the launder, there is simply no recovery.

The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
