Slate Around The World
Most slate in Europe today comes from Spain, the world's largest producer and exporter of natural slate, and 90 percent of Europe's natural slate used for roofing originates from the slate industry there.
Slate is abundant in Brazil, the world's second-biggest producer of slate, around Papaios in Minas Gerais, which extracts 95 percent of Brazil's slate.
China has vast slate deposits; in recent years its export of finished and unfinished slate has increased. It has slate in various colours.
Deposits of slate exist throughout the Australian continent, with large reserves quarried in the Adelaide Hills (Willunga and Kanmantoo) and the Mid North (Mintaro and Spalding).
