gives 32% solids in the cell which is a typical float plant feed density. In this case the laboratory mill should be set-up for 1.0 kg of sample as it is practical and best to mill the same mass of sample that will be used in the subsequent flotation test. The LabTech Essa flotation cell has a live volume of 2.0 l. To float at between 30 and 35%

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 ...

The scale-up relationship was developed based on dimensionless parameters. First, a scale-up factor (ξ) was defined as the ratio between the actual flotation rate (k AC) of the collection zone in a perfectly mixed industrial cell (N = 1) and the flotation rate (k B) in a laboratory batch cell, (1) ξ = k AC k B The apparent flotation rate constant for the …
