High Pressure Acid LeachCaldera Engineering

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 Great Laterite Challenge Why Scaling Class 1 Nickel

However one common processing step in laterite operations producing Class 1 nickel is high pressure acid leaching (HPAL). HPAL entails laterite ore being fed into an autoclave along with sulfuric acid at temperatures up to 270°C and pressures up to 725 psi to separate the nickel and other byproducts (e.g. cobalt) from the ore.
