Flotation in boat hulls

A simple series of calculations or the use of a pocket calculator can determine the volume of foam flotation required to provide flotation capabilities to an object. The terms used for these calculations are as follows: W = Weight in lbs. of object in air S = Specific gravity of object PB = Portion of weight in lbs. with positive buoyancy

Up-scaling of froth flotation equipment

Mixing zone: Zone around the impeller of the flotation cell in the test work of this research located in the cell bottom. Quiescent zone: Laminar flow zone of pulp between the mixing and froth zones of the flotation cell through which loaded bubbles rise to the top of the cell. Responses: Test results being compared in a factorial design test.

How to Calculate Buoyancy (with Pictures) - wikiHow

To calculate buoyancy start by figuring out the volume of the submerged portion of the object. Next identify the density of the fluid by using reference materials you have on hand. The deeper the solid object is submerged and the higher the density of the fluid the greater the force of buoyancy. Then find the force of gravity.

For a testwork laboratory treating a wide variety of ores the most useful laboratory flotation machine is probably one with cells of 500 1000 and 2000g capacities with a different diameter impeller for each cell with stainless steel or rubber-covered impellers glass or plastic cell bodies and requiring an outside source of low-pressure air.

Trends with Selection and Sizing of Large Flotation Circuits ...

Flotation rate of particles with varying feed floatability Flotation response = particle characteristic x cell characteristic k = P S B R F where P = a parameter related to ore floatability S B = the bubble surface area flux (=6J G /d 32) R F = a froth recovery factor The bubble surface area flux is defined as the total surface area of

Calculate Flotation Cell Capacities Volume vs Retention Time

Adding 15% as a volume factor for aeration the estimated flotation cell volume needed will be 290 cubic meters. If cells of 29000 Liters volume are chosen N will be 10. Similarly calculating for the 5-minute conditioning time at the same pulp density gives (see below).

cell to the next cell in a bank. As a result we will treat the cells in a bank as a single entity and for the purposes of this paper the term bank will be used to refer to either a single flotation cell or a bank of flotation cells. In each row the concentrate is collected in a common launderertypically for the rougher section and a separate ...

Dissolved Air Flotation Design Calculations Spreadsheet - Low ...

An example dissolved air flotation design calculations spreadsheet is partially shown in the image below. This Excel spreadsheet can be used to calculate A/S the needed air to solids ratio and the required DAF area based on user input information on influent design flow and characteristics.

Three Part Section 4. Buoyancy of Pipelines COMMON DESIGN ...

1) The possibility of pipe flotation exists when the pipeline is constructed in areas which will be inundated such as stream crossings flood plains and high ground water areas. When such conditions exist evaluate the possibility of pipe flotation. 2) The buoyancy of a pipeline depends upon the weight of the pipe the weight of the volume of


resemble the conditions in flotation (Cheng and Holtham 1995) which compared favorably with previous theoretical work (Nutt 1960). Attachment and detachment efficiencies have also been described from calculation of the bubble-particle interaction forces in flotation and used to identify a maximum floatable particle size (Ralston et al. 1999).


In a flotation plant the separation of mineral from waste is only about 85-95% efficient and is dependant upon a myriad of parameters encompassing the quality and characteristics of the ore the operating environment the reagents and the mechanical effectiveness of the flotation cells.


8. The factor of safety against flotation is the total weight resisting flotation divided by the total "buoyant force". 9. This program assumes a Factor of Safety >= 1.2 to be satisfactory taken against the highest anticipated water table level. This also allows for some uncertainty in the contributing factors and variables.
