On Limits to Flotation Cell Size

Mechanical cells have seen an exponential increase in size over the past 60 years. However, a possible size limitation due to carrying capacity constraints has been raised. Taking a Cu porphyry case, a cell sizing exercise is used to show that possible size limitation due to carrying capacity can be tested using available techniques. A range of conditions is explored …

Advanced Techniques on Fine and Coarse Particle Flotation

The most studied alternative is a flotation cell with a fluidised bed [8, 89]. Modified flotation columns also have crucial potential and some companies are developing cells that use methods other than fluidisation as well. A modified flotation column is a device that is generally preferred in the enrichment of coarse-sized (1–2 mm) ores.
