Refining gold from ore or concentrates is done during the smelting process. During this process flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make flux for gold refining by first obtaining all of the

2013-9-4douglas23 Gold or even silver can be cleaned up a little bit slightly in a melt with flux but in reality the improvement is only minor basically and even if you tried it with the placer gold you still would most likely not improve the gold to make it workable enough to make jewelry out of the impure gold

Old gold is a popular source of materials to make new jewelry including rings. Melt down any scrap gold old outdated or broken jewelry and turn the scrap into gold sheet or wire that can be used to fashion a ring. Put the small cut pieces of old gold into a crucible painted with borax to act as flux

2020-5-6If you have gold that is mixed with other materials then it would be best to mix flux with it before smelting. Use two pinches of flux per ounce of gold jewelry and more for dirty gold scraps. If you are going to use the potato method just add one pinch of borax into the potato hole before melting the gold. 4. Melt the gold by using a torch

Assaying and Smelting. As all the base metal salts are attacked or oxidied by the smelting flux they dissolve in the flux where they remain until the melt is poured into a mold. These base metals will end up in the slag or glass that floats on top of the gold. As in assaying the flux depends to a large degree on the composition of the

In metal refining a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax heat and a little know-how its possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore including gold

2019-6-21A typical copper ore contains between 0.5 and 2.0 copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores usually higher grade ores by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC
