Slate mining is the process of extracting slate, a fine-grained metamorphic rock that is commonly used for roofing, flooring, and various architectural applications. This rock is formed from shale under high pressure and temperature, resulting in its characteristic durability and ability to be split into thin sheets. The mining process typically involves quarrying, where large blocks of slate are removed from the earth. After extraction, the slate is cut and processed into usable sizes. Regions known for slate mining include Wales, Vermont, and Spain, where the quality of slate is highly valued in construction and design.
