It is also possible to refine gold without any large-scale equipment. In this process, nitric acid is first added to the gold that needs purification. Then, Hydrochloric acid or Muriatic acid is added to the mixture. Once the mixture settles, impurities are removed by filtering the solution.

The silversmith and the goldsmith start their work with impure silver and gold ore. Through the refining process they extract and mold the pure gold and silver by removing all of the impurities in the ore. This process involves fire and the close attention of the smith. The smith puts the ore in the fire to burn out some of the impurities, then takes it out and shapes it, then back in the fire ...

The refiner takes either the sample or the entire portion of gold and mixes it in a crucible with a flux (soda or borax) and lead or silver. The flux lowers the melting temperature of gold, making the process somewhat easier to complete, and the lead helps to collect the pure gold from the alloy. The Refiner Heats the Sample

The method known as "fire assay" is the oldest known method of assaying gold and continues to be one of the most accurate. When gold is melted, a sample of the gold is taken, either by drilling through the poured bar or by capillary tube sampling while the gold is in a molten state. The sample is weighed very precisely, and the amount recorded.

According to the World Gold Council, the Miller process uses gaseous chlorine to extract impurities when gold is at its melting point. Impurities separate into a layer on the surface of the molten purified gold. While the Miller process "is rapid and simple," the Council notes, it produces gold that's only about 99.95-percent pure.
