Jun 02, 2010· This video was produced by Newmont Mining Corporation and gives a general overview of gold mining in Nevada from extraction to reclamation.
Gold concentrate is combined with a flux, such as borax or other materials of mixtures, in the crucible. The flux acts to decrease the melting temperature and viscosity of nongold minerals in the concentrate so they are more easily separated from the gold during the cooling process. Small amounts of concentrates, usually around 50 to 100 grams ...
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.
In contrast to the use of mercury (which relies on amalgamation of the gold to coalesce it and separate it from impurities) this method relies on borax''s ability to lower all the minerals'' melting points. Since the gold is usually the heaviest of these minerals, it allows for concentrating the gold .

Precious metal scrap such as placer gold, dental gold scrap and gold metal foil is weighed and then smelted. As the gold scrap liquefies in the furnace, borax and soda ash are mixed in to separate the pure gold from other precious and nonprecious metals. A sample is removed for assaying, which is the process of measuring the gold content.
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined.

Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass — which will have floated to the top during the cooling process — and there is your gold, smelted to perfection.
