How is gold refined into high-purity bullion? | Provident
It's not uncommon for gold to go through the heat process as an initial step, then undergo the chemical process if a higher level of purity is desired. Low-purity alloys like 14 Karat (i.e. 58.3% purity) might be suitable for jewelry, but certain applications (like exchange-traded gold or use in electronics) require a purity of 99.99%.

Zone Refining
Zone refining refers to the method of purifying a crystal wherein a thin region of the crystal undergoes melting. This 'molten zone' is now moved across the crystal. The impurities in the metal are melted at the forward edge by the molten zone and move through the block of metal, leaving the solidified pure element behind.
