How Raw Nickel Ore is Refined into Stainless Steel | The Complete Industrial Process
Every year, humanity mines three million tons of nickel worth fifty billion dollars—a gray-green rock buried hundreds of feet underground that makes stainless steel possible. This documentary reveals the complete journey from explosive quarries in Indonesian jungles to electrolytic cells producing 99.95% pure metal—we show how raw laterite ore transforms through crushing, smelting at 2,700°F, chemical baths in sulfuric acid, and high-voltage electrolysis. Without nickel, skyscrapers would rust, submarines would corrode, and nuclear reactors couldn't exist—this is the metal that conquered time and corrosion, turning ordinary iron into material that lasts decades without a single spot of rust.
