Plant design considerations for automatic pressure filtration of flotation concentrates

A prerequisite for good filter performance is that the total filter installation has been well designed. In this sense, the filtration testwork will provide scale-up data, and an insight into the relationship between operating parameters that may then be optimised, and used in the development of a control strategy. A good understanding of the filter’s operating principles will ensure correct selection and sizing of ancillaries, allowing in particular for the difference between instantaneous and average flow rates.
