Heap-circuit design and consultancy
Copper heap leaching at Navid Farayand Alborz, Parandak is one of Zarfaravar’s design and consultancy engagements. It belongs to the same site as the cathode plant but has a separate scope.
The engagement focuses on the heap circuit and copper-bearing solution production. The circuit’s role is to leach copper from mineral feed and provide solution for subsequent recovery stages.
Pregnant leach solution as the output
The stated heap product is pregnant copper leach solution, or PLS. This is the output of the leaching stage and differs from the copper cathode produced later in the recovery chain.
Feed scale and site relationship
The listed heap feed capacity is 120 tonnes per hour. This design and consultancy engagement complements Zarfaravar’s work on the cathode plant as another part of its engineering services at Navid Farayand Alborz.
