Gold Recovery: 8 Steps (with Pictures)

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 increases.
