    Dressing, or the concentration process, normally begins with crushing and grinding. In certain cases, pre-dressing is done, which means that coarse waste particles are separated from the ore flow at an early stage of the process. In iron mines this can be done by dry magnetic separation and in other cases there are also optical separation
