Gold Recovery : 8 Steps (with Pictures) - Instructables

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 ...

Smelting and Roasting Ores to recover gold, silver and ...

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.
