Slate Industry

The slate industry is the industry related to the extraction and processing of slate. Slate is either quarried from a slate quarry or reached by tunneling in a slate mine. Common uses for slate include as a roofing material, a flooring material, gravestones and memorial tablets, and for electrical insulation. Slate mines are found around the world and the major slate mining region in the United Kingdom is Wales: in Cornwall there are a number of slate quarries (famously the village of Delabole) and in the Lake District there are numerous slate mines and quarries.

90% of Europe's natural slate used for roofing originates from the Slate Industry in Spain.

In the remainder of Continental Europe and the Americas Portugal, Italy, Germany, Brazil, the east coast of Newfoundland, the Slate Valley of Vermont and New York, and Virginia are important producing regions. The Slate Valley area, centering on a town called Granville in the state of New York is one of the places in the world where colored slate (i.e. slate which is not grey or blue) is obtained.
