As Nadu Mining, we provide high-quality raw perlite ore, the cornerstone of numerous industrial and agricultural applications. Raw perlite is a naturally occurring amorphous volcanic glass, formed by the hydration of obsidian over millions of years. This unique mineral is renowned for its remarkable ability to expand, thanks to the water trapped within its structure, making it an indispensable raw material across countless sectors.

The raw perlite we carefully extract from our mines is crushed, screened, and graded into various particle sizes. Even in this unexpanded state, it serves as a valuable material: a lightweight aggregate in construction, a slag coagulant in the foundry industry, and a water-retention agent in landscaping. However, the true potential of raw perlite is unlocked when it is exposed to high temperatures.

When heated to approximately 850-900°C (1560-1650°F), its internal water turns to steam, causing the ore to expand up to 20 times its original volume. This process yields expanded perlite—an incredibly lightweight, porous, and sterile material. This transformation turns raw perlite ore into a versatile resource used for everything from soil aeration in agriculture and thermal and acoustic insulation in construction to filtration aids and fillers.

As Nadu Mining, we are proud to supply pure, consistent, and high-quality raw perlite ore, the very starting point of this miraculous transformation. The right foundation for your projects begins with our perlite.
