  • How To recover Gold From Digital Waste

    The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners.

    Gold-plated material is also worth processing, but it depends on the type of material and volume. Small amounts of gold-plated jewelry are not worth recycling, but if you have 50-100 pounds of mixed gold-plated jewelry, it could be worth processing. Gold-plated electronic scrap is also worth processing if you have 50 pounds or more.

  • Using Borax Flux to Refine Gold

    Aug 07, 2013In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.

  • Borates in Metallurgy and Gold Refinement

    The borax contribution to flux composition can be up to 60% of total flux weight but is typically around 30-40%. Borates are also used to facilitate the attack of gold ore at a lower temperature and to make the slag more fluid at the furnace operating temperature, thus reducing viscosity.
