High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore. HPAL has been used since 1961 when it was ...
The DNi Process TM is a ground-breaking, patent-protected method for extracting nickel, cobalt and other constituent metals contained in laterite ore. Ensuring the sustainability of natural resources, our process maximises extraction, minimises cost, minimises residue and realises the full polymetallic value in earth's lateritic resources.
