The plant was designed for processing 1,838 tnm per day or copper ore and 25.7 tnm or molybdenum ore (as oxides), and includes crushing, grinding, floatation, concentration, and thickening.
From January 2010 until July 2011, Aker Solution (EPCM) contracted Lepsa for the engineering, and manufacture of fifty (50) process and reactor tanks for the concentrate plant.
