Principle of Zone Refining. The principle of zone refining is that the impurities in an ingot or ore of metal are more soluble in the melt statepared to the corresponding solid state of the impurities. In the zone refining process, the impurities are concentrated at one end of the block of metal so that the rest of the block is purified.
