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.

01.02.2013· The dissolution kinetics of nickel content from zinc plant residue in sulphuric acid was investigated. It was found that the nickel extraction enhanced with the increase in sulphuric concentration, temperature and leaching time. The decrease in the particle size and solid to liquid ratio increased nickel dissolution. The extraction rate increased with increasing stirring speed and it was .
