This video documents the smelting process of gold ore concentrates, provided by Dan Hurd. The video follows Jason as they use a furnace and various fluxes to separate the gold from the other materials. The process involves melting the concentrates, adding a collector metal, and then using a cupel to refine the gold.

This video demonstrates a process for extracting gold from raw quartz ore. The process involves crushing, concentrating, and refining the ore using a combination of mechanical and chemical methods. The video highlights two refining techniques: direct cupellation and direct smelting, both of which are mercury-free and chemical-free.

The video follows a prospector as they process a large amount of ore, panning for gold and then smelting the concentrate. The process involves mixing fluxes, loading a crucible, and using a furnace to melt the material. The prospector encounters challenges, including a frozen tank and a flux that expands significantly.

This video explores the process of gold smelting, focusing on the effectiveness of different flux recipes and the use of bismuth oxide as a collector metal. The creator tests various combinations of ingredients and analyzes the results, including the amount of gold recovered and the potential for loss due to bismuth alloying with steel. The video concludes with a promise to reveal the results of larger smelts in a future episode.
