Abstract

In accordance with the present invention there is provided a method for leaching zinc from a carbonate-hosted ore, the method comprising the method steps of: applying an aqueous solution of a curing agent to the carbonate-hoste ore, producing a cured ore; forming a leach solution by applying an ammoniacal solution that has an ammonium carbonate content of less than 5 g/L to the cured ore, producing a pregnant leach solution; and passing the pregnant leach solution to a means for recovering zinc.
