STAL Technology: Revolutionizing Nickel Processing

STAL Technology logo for sustainable nickel production

At TGEM, innovation drives sustainability. STAL Technology is a proprietary hydrometallurgical process that enables sustainable nickel production from laterite ore and industrial waste materials, such as spent catalyst and electronic waste. With a zero-waste approach, STAL maximizes resource utilization while minimizing environmental impact. As a result, it offers a scalable, sustainable solution for nickel production.

Initially designed for laterite ore processing, STAL Technology now also enables efficient nickel extraction from industrial waste materials, further enhancing sustainability and resource efficiency.
