Flotation

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.
