Mining for ore. Engraving of a water-powered mine at Freiburg,Germany,in the 16th century. This project was led by the German mineralogist Georgus Agricola. A water wheel (at left) provides the power to lift buckets full of rocks and metal ore out of the mine below. The water wheel,and therefore the lifing mechanism,is lever- controlled by a man stationed in a box at upper left | |
