Jan 18, 2017· Refining Gold . Smelting is not always the final stage in gold extraction. Depending on the intended use of the gold, it may have to be refined before being put to use. Refining gold is simply the process of removing the finer impurities that the smelting process could not remove. There are several methods used to refine gold.
When refining silver you want to make sure you do this outside where there is plenty of ventilation. Give yourself plenty of room in order to have a quicker dissolving reaction from the silver. Depending on how much silver you have to refine will depend on how many 5 gallon buckets you will need.

The ancient process of refining gold has already been described under METALLURGY (which see). Most of the Bible references are to the refining of silver (Proverbs 25:4 Zechariah 13:9 Isaiah 48:10). The silver used by the ancients was probably obtained by smelting lead sulfide ore, rich in silver (argentiferous galena).
It also plays an important role during the gold refining process as a flux. In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to ...
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
