  • High Pressure Acid LeachCaldera Engineering

    Overview. 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.

  • Basics of LeachingSeparation TechnologyArticles

    Simply put, leaching generally refers to the removal of a substance from a solid via a liquid extraction media. The desired component diffuses into the solvent from its natural solid form. Examples of leaching include the removal of sugar from sugar beets with hot water and the removal of nickel salts or gold from their natural solid beds with sulfuric
