• The Borax Method is a technique of artisanal gold mining

• Its basic principle is borax powder reduces the melting point of all minerals, including precious metals like gold.

• The melting point of gold is 1063 ˚C, which is unable to be melted by normal torches and burners.

• By adding borax powder to the heavy mineral concentrate, the melting point temperature decreases.

• Thus, this method allows people to melt gold out of their concentrate and salvage.

• By using borax powder, no mercury flour is produced, and gold recovery increases.
