Application of Computerized Models for Optimizing

Development of automatic control systems of flotation process remains rather promising way of increasing effectiveness of ore concentration process. Without ore averaging systems flotation process is characterized by considerable fluctuations of all input, output and intermediate parameters. According to estimates, instability and nonoptimised parameters of flotation owe 3% to 6% of

Application of Fuzzy Control to a Flotation Process

The application of fuzzy logic in the control of flotation is studied in this paper. A general description of apatite flotation process is given and a dynamic model is developed. A fuzzy logic controller is proposed for a nonlinear isolated continuous flotation process. The knowledge base of the controller is constructed on the basis of the

A review of froth flotation control ScienceDirect

Process control system level hierarchy for flotation which is prone to non-linear, complex behaviour. As such, many predictive flotation control systems often (but not always) include adaptive control aspects. By 1991, Thornton noted that although the amount of literature devoted to multi-variable model-based control was extensive, the number of applications in industry was still

Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Frothers & Froth Flotation ArrMaz

During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations. These characteristics play an important role in the

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
