FLOTATION CONTROL & OPTIMISATION

Flotation is a complex process that is affected by a multitude of factors. These factors may be inherent in the circuit design, or in how the flotation plant is operated. The FloatStar suite of control modules utilises advanced process control to overcome design-related limitations and maximise circuit performance during operation.

Flotation stabilization and optimization

level control rather than on the optimization of a circuit that was not stabilized. Process control and optimization have a direct influence on the efficiency of flotation plants. An inefficient operation can cause an incorrect balance between grade and recoveries and can also lead to adverse shifts in the grade-recovery relationship.

TECHNICAL NOTES 9 FLOTATION Mineral Tech

8.1 A Kinetic Approach to Flotation Modeling Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment

Soft computing-based modeling of flotation processes A

Dec 01, 2015· However, despite this trend, it is also clear that the obstacles in constructing and utilizing an ANN model or ANN/hybrid-based controller in a flotation plant, are present, since only one paper mentions the actual construction of an ANN model-based controller (controlling the interface level of a flotation column, Mohanty, 2009).

Effect of the objective function in the design of

Aug 01, 2014· Cisternas et al. (2004) developed a procedure for the design of flotation circuits based on mathematical programming using a two-level hierarchized superstructure. This procedure assumed that the flotation can be modeled using a first order kinetic model. The method was then applied to a copper flotation plant.

In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.

Dissolved Air Flotation Systems

Dissolved Air Flotation systems effectively remove TSS, FOG, and other pollutants from wastewater. Conceptually, the DAF process is simple tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water but designing a DAF system for a real-world application isn’t quite as simple.
