:: Selecting Flotation Cells: How Many and What Size? Lower ore grades have driven the industry to larger throughputs and thus larger equipment over the last 20 years Flotation cell sizes of up to 200m 3 are now available with 150m 3 cell installations being common

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing, paper 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

The design of Denver Sub A flotation cells incorporates all of the basic principles and requirements of the art, in addition to those of the ideal flotation cell Its design and construction are proved by universal acceptance and its supremacy is acknowledged by world wide recognition and use

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles with attached air

Provision to remove froth by the use of froth paddles on all flotation cells should be included in the original design The additional capital cost required for froth paddles is a reasonable investment since these devices tend to negate errors in flotation pulp level or frother addition

Flotation circuits often consist of very large cells and variable stream flows Often, the operation of industrial cells cannot be easily changed for plant trials, and its almost impossible to measure the outcome of any change Xinhai has developed a 3m³ test cell to enable flotation testing at a realistic scale The rig allows key

Real time flotation level monitoring, done on each bank of flotation cells, is clearly the solution, but using the proper measuring instrument has had its own challenges Particle buildup on the measurement instruments and the issue of going inside the flotation cell to take measurements of the froth column are particular cases in point One

Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell The sparger technology is an important design choice, and allows the user to optimize the

Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks Rougher and scavenger banks are focused on recovery and thus provide maximum residence time Rougher banks can be large with the number of cells being 5 or greater
