The island of Milos is one of the world's most significant sites for the extraction of industrial minerals, specifically perlite and bentonite. The island's mining tradition dates back to the Neolithic period when Milos was the primary source of obsidian in the Mediterranean. Today, these volcanic minerals form the bulk of its exports, making Greece one of the leading global producers in the sector. The perlite mines are mainly located in the northern and eastern parts of the island, characterized by extensive open-cast pits. Once extracted, the mineral is crushed and often processed locally before being shipped worldwide for use in construction, horticulture, and filtration. Mining is the most vital economic pillar of the island alongside tourism, providing employment for a large portion of the local population. Despite environmental challenges, the industry operates under strict regulations to ensure the gradual restoration of the landscape.
