If the purpose is to refine all of the gold, however, this will be done on a much larger scale. 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
