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 ...

OPTIMIZING THE OPERATING CONDITIONS OF GOLD …

The continuous decrease of gold content in the stream and the variability of flow rate and temperature affect the elution and electrowinning processes. Low-grade eluate tends to be problematic for electrowinning as the impurities tend to “compete “with the gold for deposition current.
