How Medieval Miners Extracted Gold With Fire and Water (No Chemicals)

Discover how medieval miners extracted pure gold from quartz rock using no chemicals—only fire, water, and gravity. In this deep dive, we reverse-engineer their forgotten methods, from identifying gold-bearing rocks to smelting with charcoal and clay. This video explores: ⚒️ The 3 Physical Clues medieval prospectors used to find gold in quartz veins (iron staining, weight, location). 🪨 The Crushing & Panning Process: How they liberated gold using its unique malleability and extreme density. 🔥 The Fire Method: How they used a simple charcoal fire in a clay crucible to break down sulfide minerals and release trapped gold. ⚱️ Ancient Purification: The cupellation and acid process used to achieve nearly pure gold for coins and jewelry. ♻️ Why These Methods Still Matter: A sustainable, non-toxic alternative to cyanide and mercury used in modern industrial mining. We break down the step-by-step physics that made it possible, proving these pre-industrial techniques are still effective today for small-scale, artisanal, or survival mining. Learn the engineering principles behind gravity separation and thermal decomposition that require no modern chemicals. If you're interested in historical gold mining, sustainable precious metal recovery, survival skills, or medieval technology, this documentary-style analysis reveals the ingenious physics our ancestors mastered.
