2020-6-11  In this case, the flotation operator should decrease the feed density, adjust grinding and classifying processes or adjust the reagent dosing or air injection to keep the slurry level at a certain point. An in-line density meter can be used to check in real-time the amount of ore in the feed (

How to Measure Density of Floating Object (5 Steps)

2016-5-7  Calculating the Density of Floating Object:-. We measure the mass of object by weighing it and Volume is the level of water that we got in Beaker “A”. If we divide the mass obtained by this volume, we will get the density of the object and that too very much accurate if we do not make mistakes in calculations. 4. Some More Facts to be ...
