Low-grade manganese ore is beneficiated with hydrochloric acid as a leaching agent to obtain a manganese concentrate. Hydrochloric acid can then be regenerated using cheaper sulfuric acid via contact with the leach liquor (a CaCl2 solution), whereas calcium sulfate whiskers can also be precipitated during this regeneration.
