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 ...

In the lab cell, this is approximated with the cycles, e.g. the number of times the total volume of the feed passed through the cell. As an example, a feed volume of 30 L fed at 5 L/min into the lab Concorde Cell means that a single cycle last 6 min and as such, a flotation test of 18 min is equivalent to three cycles. 4.
