·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
·The Reflux flotation cell RFC is a relatively new flotation technology that has been invented by the group of Prof Kevin Galvin from the University of Newcastle in Australia and developed by FLSmidth RFC is in fact an inverted gravity separation system known as the Reflux Classifier RC which combines a conventional fluidized bed
·After the pulp and flotation reagent are fully mixed they are sent to the flotation column through the central feeding device The pulp is slowly descended under the action of gravity and the compressed air is dispersed into a large number of tiny bubbles through the inflator which are evenly distributed on the entire section of the column and rise slowly
·If on the other hand flotation is to be attempted with but little agitation intervening following the introduction of the oil a mobile and relatively soluble oil must be used The quantity of oil necessary in any froth flotation operation depends upon the kind of oil used; the recoverable mineral content of the ore;
