| Summary |
To extract precious metals found beneath the earth requires a massive 232-ton, two-story-tall dump truck with a load capacity of 320 tons - a giant earth-mover like the Komatsu 930E. This amazing engineering achievement is made possible by five essential raw ingredients: coal, chromium, mineral oil, latex rubber and sulphuric acid, an electron superhighway that generates massive power. |
