    Well done, Jason! In addition to Portland cement (calcium oxide) you could use ground glass or calcium phosphate (available as a fertilizer or bone meal) or crushed magnesite. The problem with using glass is that gold is soluble in molten glass just like lead oxide is. If you were to use bone meal fertilizer, you would first have to burn off all the left over organics like fat which smells bad and smokes a lot. If you used copper as the collector metal while processing the original gold button, you may find a lot of copper remains distributed throughout the final gold button (to be determined with a quick x-ray analyzer). Gold and copper form a pretty strong marriage if inadequate amounts of flux are used. I wish more video authors discussed gold ore processing options like you have done so people wouldn't expose themselves to mercury, vaporized lead, cyanide, nitric acid, and a bunch of related compounds that form during the processing. Again, I must say: "Well done, Jason!"

    Qouted = Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from limestone

    Hi there!!! I need help. I want to refine gold out of 500 gramms of copper, Bronze, silver and steel. Can I refine it by melting it down and pouring it inside of this pyramidical mold?

    There must've been some gold in that lead, because the finished product is bigger than what you started with.
    My Dad said to use mercury to gather the gold, and then the mercury needs processed to get out the gold from it. Can't quite recall the process how he said to do that..long time ago..
