Phlogopite mica from Madagascar is renowned for its high quality and diverse applications. Discovered in 1912, Madagascar has become one of the leading exporters of phlogopite mica. This mineral is typically found in shades of brown, yellow, green, and gray, and is used primarily in the electrical industry for insulation and capacitors. The sustainable extraction and processing of phlogopite mica scrap in Madagascar ensures minimal environmental impact while supporting the local economy. This makes it a valuable resource for various industries, balancing economic benefits with ecological responsibility
