Solution. Zone refining: This method is based on the principle that impurities are more soluble in the molten state of metal (the melt) than in the solid state. In the process of zone refining, a circular mobile heater is fixed at one end of a rod of impure metal. As the heater moves, the molten zone of the rod also moves with it.

Solution. Zone Refining method is based on the principles of fractional crystallisation. When an impure metal is melted and allowed to solidify, the impurities will prefer to be in the molten region, i.e. impurities are more soluble in the melt than in the solid-state metal. In this process, the impure metal is taken in the form of a rod.

15.03.2022Metal zone refinement is a method of refining in which a circular mobile heater is mounted to one end of an impure metal rod. When the heater moves, the molten zone of the rod moves as well. This motion causes the creation of pure metal crystals from impurities, which are then transmitted to the opposite side of the molten zone.
