maxflot says a typical deficiency of mechanical and conventional pneumatic flotation cells is the inability to float particles larger than 0.42 mm, due to the weak bubble structure produced by both mechanical after several years of laboratory and field evaluations, flottec has established that each frother has its own unique relationship among bubble size reduction, gas hold-up increase, froth stabilisation and frother
froth characteristics are also known to play a role during up-scaling from batch to continuous. processes, since froth recovery is approaching 100% in batch flotation and ranges between. approximately 50 and 80% in industrial flotation, for example 66,2% found by yianatos et al. (2008a).
