Step 4 - Observe the Gold Separating. Continue to heat the slag until you can observe the molten gold begin to dissolve away from the rest of the slag. This occurs because of the melting point and the density of the gold as compared with the different melting points and densities of the other metal components of the slag. The gold should slip ...
To cheaply smelt your own gold you need to have access to a high temperature furnace. For a do-it-yourselfer this shouldn't pose a huge challenge. The first thing to do is determine the amount of gold to smelt. This will inform the size of the furnace. Small tin coffee cans or large trash cans make for good starting points in this regard.

Gold jewelry can be melted using the following methods: propane torch, gold melting machine, resistance furnace or a 1200 watt microwave oven. Of all the methods of melting gold jewelry, the gold melting machine method is highly recommended. The gold melting machine is highly efficient for both small and large size gold production.
Start by obtaining as many scrap electronics components to reclaim gold from. Generally speaking, older electronics work better because enhanced manufacturing processes use less gold than older electronics, so an old 386 or 486 computer, for example, contains more gold than a modern computer.
Gold, precious forever but especially lately, is a tricky metal. Bound up in consumer electronics, jewelry and the ores that it comes from, gold is …
Placer mining / ˈ p l æ s ər / is the mining of stream bed deposits for minerals.This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment.. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in ...
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the gold-plated metal parts in the circuit boards using a magnet.
The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.
