Flotation process audit and bottleneck identification
The maximum possible recoveries achievable with the ore can be estimated from the kinetic laboratory scale tests. A kinetic flotation model is then fitted to the test data. The model solves mass portions of floatability classes – typically fast, slow and non-floating – and gives the associated rate constants for each mineral.
