Significance Of Comminution Circuit Design

There are many grinding schools in the mining world, which claim their grinding method to be the best possible - and still the methods concerned vary a great deal. Some of them have multi- stage crushing and only single stage grinding while in others crushing may be nominal, but grinding can be very complicated. - In this presentation firstly the nine most common comminution circuits will be analyzed. Then results from a pilot scale test series will be reviewed, in which nickel ore ground by four different comminution methods was fed to a common flotation treatment.
