The processing of ores often entails use of unit opera-tions such as grinding and flotation. Typical production requirements in mineral processing plants include the maximisation of throughput, maintenance of desired product quality and reduction of operating costs. For optimising plant performance, redesigning a process route is often impractical and the problem is best addressed …

Flotation Circuit Process Control

Jun 08, 2016 Routine Control in a Modern Flotation Plant. We will now study control in a modern flotation plant. First, we will assume that before this plant was built, a thorough ore-testing campaign had been completed and detailed knowledge obtained of ore characteristics. Economical grinding limit had been determined and a suitable reagent balance decided.

Dec 26, 2018 Flotation is a two-stage process involving the levitation of particles and water from the pulp to the froth phase, and their subsequent transfer to the concentrate launder. Not all of the materials that report to the froth phase eventually proceed to the concentrate launder; some drain back to the pulp.

Model based feedforward control scheme for flotation plants

An advanced model-based control scheme is presented here as a promising solution to this control problem. The main feature of this control scheme is the real time identification of the unknown disturbances in the first few cells of the flotation circuit. This information is used to control the rest of the flotation plant in a feedforward fashion.

Flotation control A multivariable stabilizer

Dec 31, 1995 Abstract. This paper presents a stabilizing controller for flotation plants which uses a quasi-multivariable technique. The controller monitors all the levels in the plant, and by anticipating interactions between various parts of the plant, is able to stabilize the plant far more successfully than the normal plant control.

Model Predictive Control (MPC) An optimization routine for a flotation circuit must first begin with mastering level control even in the presence of disruptions (waves, etc). Ideally, a level control system would adjust downstream levels preemptively to account any upstream disruptions before the effects of the disruptions propagate downstream.
