STAL Technology™, or Step Temperature Acid Leach Technology, is an innovative and highly efficient, zero-waste Hydrometallurgy-based technology to recover metals and minerals in lateritic ores without environmental impact.
Designed to produce high-grade nickel, cobalt, and other valuable products, the technology offers one of the lowest capital and operating costs among other current technologies. STAL Technology™ has been tested and validated to provide the most effective and profitable process in treating an entire profile of a laterite deposit, from low-grade Limonite to Saprolite and any transition zone. The technology has gained nationwide recognition for its potential in accelerating the Indonesian government’s nickel-based downstream industry plan.
Through further research & development, HMI strive to maximize the value of limonite ore in a Nickel-based value chain
