Jan 01, 1993 · "An Expert System has been implemented to assist operators in applying knowledge about froth conditions in the control of the flotation circuit at Highland Valley Copper. For some time, the personnel at Highland Valley Copper have recognized that froth type is a useful indior of good operating conditions.
Flotation Cell Control International Mining. A key part of successful plant control is the operation of the flotation circuit Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) air addition rate Many other parameters may vary such as feed rate particle size distribution
The Froth Recovery Package enables you to better control the froth phase, which in turn improves the performance of the flotation cell. The addition of the radial froth crowders adds a new dimension to the control strategy. It allows you to shift the grade recovery curve by allowing either deeper froth or faster froth .
Duration: 4 days Limit of 10 participants. Following this training, the participant will be able to master the basics of instrumentation, focusing on installation, calibration, troubleshooting and configuration.
In froth flotation, separation between the valuable and the gangue minerals comes as a result of the attachment of hydrophobic particles to air bubbles. Considering the importance of bubble formation and bubbleparticle attachment, it is evident that the pulp phase facilitates the events for the most crucial requirements of successful flotation.
Effective fault detection techniques can help flotation plant reduce reagents consumption, increase mineral recovery, and reduce labor intensity. Traditional, online fault detection methods during flotation processes have concentrated on extracting a specific froth feature for segmentation, like color, shape, size and texture, always leading to undesirable accuracy and efficiency since the ...
Sep 15, 2005 · A key part of successful plant control is the operation of the. flotation circuit. Flotation cells have three main control parameters. (1) reagent dosing rate (2) froth depth and (3) air addition. rate. Many other parameters may vary such as feed rate, particle.
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells,, m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel increases with an increase in the ...

Outokumpu has developed an operator advisory system for assisting the control of the pyrite flotation circuit at Pyhasalmi, [13]. This expert system is connected to a speech synthesizer which outputs messages for alarm conditions and for disturbances in feed conditions.
Water recovery is one of the key parameters in flotation modelling for the purposes of plant design and process control. This paper reviews some of the water recovery models available in the literature, including both empirical and fundamental models. The selected models are tested using the data obtained from the experimental work conducted in an Outokumpu 3 m3 tank cell at the Xstrata Mt Isa ...
