Is there any study to experimentally show particle trajectory of three different minerals on a single bubble under same hydrodynamics conditions?

I’m trying to schematically demonstrate the effect of particle density of minerals (quartz, chalcopyrite, and galena) on particle-bubble interaction in the presence of a single bubble. Any...

Why most of researchers in grinding simulation field, consider breakage function as normalized breakage function?

If we want to deal with grinding simulation we need to measure breakage function (BF) in lab. There are two different sorts of BF. Normalized and non-normalized. The question is, why in all cases...

Is it necessary to reach a temperature around 50 centigrade in the SiO2 Sol-Gel process?

We are using Sol-Gel process as a sub-process in our tests. Temperature of final step in this process was around 50 centigrade. However, in recent similar experiments this change has not been...
