This online calculator helps you on how to calculate or estimate either what size/volume flotation cell and well as conditioning tank + how many flotation cells your bank needs to accommodate the retention time you need. Design Retention time is usually obtained from laboratory testwork and proper use of Lab-to-Plant flotation scale-up factors.
Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results.. The retention time required for a given application is determined through balancing the necessary process parameters – particle size distribution, air flow velocity, temperature, and more – with the desired outcome; it can then ...

So we can calculate the average time a water molecule will spend in the bucket. It's the volume of the bucket 10 divided by about a litre a minute. So the water spends 10 minutes in the bucket before it overflows over the side. And that's what we call the residence time.
