Communion is the process of splitting physically different minerals present in the ore from their interlocking state. It is done by crushing the ore below a certain size and then grinding to a powder. The fineness of the powder depends upon the dispersion of the mineral of interest. Crushing is done mostly using mechanical crushers.
