  • High Pressure Acid Leach

    High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodi 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.
