Gold dissolution in iodide electrolytes, llydrometallurg.v, 26:163177. Several oxidants (hypochlorite, iodine and hydrogen peroxide) were used to evaluate the dissolu tion of gold in iodide electrolytes at ambient temperatures.
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
