Mining activities have been carried out by humans for millennia. The first book on mining, (and the health hazards associated with it), was De re metallica by Agricola, published in Switzerland in the sixteenth century. Mining is among the most hazardous of all occupations. Mining activities take place all over the world, and are often a major source of a country's natural wealth. There are many types of mining operations, ranging from precious metals, such as gold, to other metals, and to minerals such as asbestos, sand, granite, and iron ore.
