    Abstract: The effect of variable zone length on the separation efficiency in zone refining processes was investigated theoretically. During zone refining operation, properly adjusting the zone length along the ingot influences the solute concentration in the liquid zone, leading to an enhancement of the extent of separation. For multipass operations, considerable improvement in separation is obtained by adjusting zone lengths in each pass separately.
