Report on flotation pilot plant design and arrangement

2018-12-18 · To achieve an adequate flotation, bubbles that rise to the top of the flotation cell must not break until they are skimmed off to collect the floated particles. This is the reason why non-ionic surfactants are usually added to produce the desired stability of the froth. This may happen that a collector can act as a frother, such is the case

2016-2-29 · In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level. Above are illustrations of three flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu ...
