Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.

The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery ...

Melting Gold with Propane. It's difficult to melt gold with ordinary flames and domestic fires. But, can you melt gold with propane? Of course, you can because propane burns at around 1980 °C (3596 °F), and you just need to hit 1064 degrees to melt gold.
Gold Melting Furnace is used to melt gold in order to refine gold prior making ornaments. Melting gold helps separating gold from black sand, dust, rags and other unwanted materials present. This gold furnace heats gold at its melting point which is 1064°C. In addition, it is also used to melt silver.
