The cell volume of laboratory flotation equipment is much less than coal preparation plant flotation cells. As a result, the fluid dynamics differ greatly which means the dosages of the reagents (frother and collector) cannot be scaled up from the laboratory test to a pilot plant or coal preparation plant flotation cell.

The operational proof-of-concept for the flotation cell class of 500 m3 and larger is discussed in this paper. Two different sites are used as case studies and metallurgical and hydrodynamic performance is evaluated as the means of comparison. Frother selection criteria are also discussed and a redesign on standard practices for scaling up to full-scale from lab and pilot …

How the data is used to determine flotation kinetics is a subject of a separate video. The key aspects are: the types and setup of the laboratory cell; sample to be tested, test conditions and; how the test is conducted. The standard laboratory cell and cell size for many decades has been the Denver D12 with 2.5 litre stainless steel cell.
