The following tables will give some idea of the growth of mining and metallurgy in Germany.
The extraction of minerals in the German Empire, in metric tons, which are very little smaller than the English ton (0.984), was:
| 1883. Tons. | 1893. Tons. | 1910. Tons. | |
|---|---|---|---|
| Coal . . . . . . | 55,943,000 | 76,773,000 | 152,881,500 |
| Lignite . . . . | 14,481,000 | 22,103,000 | 69,104,900 |
| Iron Ore . . . . | 8,616,000 | 12,404,000 | 28,709,700 |
| Zinc Ore . . . . | 678,000 | 729,000 | 718,300 |
| Mineral salts (chiefly potash) | 1,526,000 | 2,379,000 | 9,735,700 |
Since 1894 the iron industry has taken a formidable development, the production of pig-iron reaching 12,644,900 metric tons in 1909 (14,793,600 in 1910), and that of half-finished and finished iron and steel, 14,186,900 tons; while the exports of raw iron, which were valued at £1,195,000 in 1903, doubled in seven years, reaching £2,250,000 in 1910.
