It brought the surviving experiential knowledge of the miners together with the classical school of the humanists. Mines tend to be in mountains and gloomy valleys with little economic value.

Agricola describes parting silver from gold in this book by grorgius acids. He also speaks about the different types of reefs and the way to to detect them. He then describes dowsing with a forked twig although he rejects the method himself.

Gems are found in some mines, but rarely have their own veins, lodestone is found in iron mines and emery in silver mines.

The result is a book of which there are few: The interweaving of science and technique is mainly the work of the nineteenth century. Agricola also describes several designs of piston force pumps which are mmetallica man or animal powered or powered by waterwheels.

Some of these are man-powered and some powered by up to four horses or by waterwheels. Inthe first English translation of De Re Metallica was privately published in London by subscription.
