The paper studies the control performance of the flotation process as a function of the measurement accuracy and sampling frequency of an on-stream XRF analyzer, using a simple dynamic model. An additional aim is to assess how the economical result of a mineral flotation process depends on the quality of process control based on the online elemental assays. The economical performance of the control was studied by calculating the overall net smelter return with various analyzer parameter combinations. The economical performance of the simulated process declines strongly when the sampling cycle is increased.
