The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In1932flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
The Sub-A Flotation Cellhas been applied to all types of flotation problems and these machines have continuously demonstrated their superiority. They have given very successful results through a wide range of problems, and their supremacy is fully proven by world-wide acceptance and application.The feature of the Sub-A is the design. The Sub-A incorporates all of the basic principles and requirements of the flotation process and these, coupled with the special and exclusive wear features, make it the ideal Flotation Cell.

The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells. Particles of the same mineral float at different rates due to different particle characteristics and cell conditions.
Efficient oilwater separation for flow rates 160,000 bbld. For locations that require a compact vessel footprint, the UNICEL Vertical IGF induced-gas flotation unit is a simple, hydraulically operated gas flotation machine that delivers efficient oilwater separation with complete process containment.
This invention relates to a method of controlling one or more froth flotation cells for separating substances.
This invention relates particularly, although by no means exclusively, to a method of controlling one or more froth flotation cells for separating minerals, for example minerals containing metals such as nickel and copper, from ore that contains the minerals and other material, typically referred to as gangue. The following description of the invention focuses on a froth flotation method for separating minerals from gangue, but the invention is not confined to this application.
One, although not the only other, example of a froth flotation method is de-inking of paper, wherein it is the undesired ink which is removed via the froth, and the desired paper that remains in the pulp in the flotation cell. Other examples of froth flotation methods are for protein separation, molecular separation and waste separation.
This invention also relates to a method of froth flotation in one or more froth flotation cells.
This invention also relates to a froth flotation cell and to a plant that comprises a plurality of froth flotation cells.
Mineral froth flotation is a known industrial process used for extracting valuable mineral content from ore obtained for example through mining. It is a surface chemistry process used to separate solids, typically fine solids, by exploiting the variation in hydrophilicity between different materials.
In addition, modern industrial processes make use of increasingly large flotation cells. This increase in size tends to encourage the use of increased power and air volume in flotation cells, regardless of performance considerations, increasing the inefficiency inherent in existing control and operation methods. Problems therefore remain in known practical flotation methods with respect to which variables should be observed, measured and controlled in order to optimise flotation performance, as well as how to manipulate those relevant variables accurately.
In particular, existing techniques do not provide both high grade and high recovery of the concentrate recovered from industrial flotation processes.
A discussion of investigating froth flotation performance is provided in Barbian et al, 34The Froth Stability Column - Measuring Froth Stability at an Industrial Scale34, Pages 315 to 319, Centenary of Flotation Symposium, Brisbane, QLD 6 - 9 June 2005 in which correlations are identified between a froth stability factor, air rate and froth depth in a single cell
In addition, the applicant is not aware of any known technique that can utilise straightforward and automatable measurement of parameters in order to reliably control operation of a group of flotation cells.
Bubble attachment phenomena, rather than the rate of collision or air flow, limit the rate of flotation in an ASH 3. In an ASH, separations can be achieved for residence times of about one second rather than minutes as in conventional flotation cells. The ASH consists of a vertical porous cylinder with slurry fed tangentially at the top, froth
Flocculant or flotation chemicals can assist in oil and or solids removal by Induced Gas Flotation. Technical Induced Gas Flotation Units are available for flow rates, typically from 800 - 24,000 m3day 5,000 150,000 BPD, although any specific size can be catered for. Each IGF system consists of
Dissolved Air Flotation Theory of Operation. If you are unfamiliar with basic DAF separator design principles, a review of the quotDissolved Air Flotation Theory of Operationquot might prove helpful.This basic document covers Stokes law and other basic separation concepts.
