(GOLD) SMELTING USING A MICROWAVE AND A PROPANE FURNACE

Smelting gold ore using a microwave and a home made furnace. The first step is to separate the silicates buy melting the concentrated ore. Then pouring it into a cone mold so that the metals sink to the bottom of the mold then placing the mixed metals in a bone cup and heating it so that the lead will oxidize and soak into the cup leaving the precious metals behind which have a much higher melting point that lead, zinc, and tin. #gold #goldmining #goldmine
