The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution. 4 Use the pulp-in-carbon method by which you should combine carbon with gold to get carbon gold particles. 5 Put the carbon gold particles into the caustic carbon solution to separate ...Gold will dissolve into tin (or solder) at a very low melting point, and form an alloy of a lower melting point than gold alone... The more metals in solution the more problems you will encounter separating metals out chemically, some metals can also make separation difficult if not impossible by normal chemical precipitation or metal ...

The more pure the gold, the more valuable it is. The process of smelting is how gold is separated from impurities, with the end result being solid gold. It is possible to melt your own gold, with the proper equipment. If doing small amounts, like melting down broken jewelry, it is possible to even use a 1200 watt microwave to do the job.Method 1Method 1 of 3:Getting the Right Equipment.

There are minor exceptions such as cupellation, but you are not relying on heat alone----you are oxidizing the lead, which is then absorbed, along with oxides of other base metals, in the cupel. One does not purify precious metals simply by heating. If you introduce chlorine to the molten metal, that's a whole different world.The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together. The gold ore is then pulverized using pressure to create very fine particles. These fine particles are then heated in a furnace to temperatures above 1064 degrees Celsius the melting point of gold.

Gold jewelry can be melted using the following methods: propane torch, gold melting machine, resistance furnace or a 1200 watt microwave oven.
