Los Filos Bermejal is a 24 million tonne/year heap leach operation with a 3500 m3/hr ADR plant.  KCA provided metallurgical flow­sheet development, followed by the process sections of a bankable feasibility study.  KCA supplied detailed engineering, procurement and construction management services for the ADR plant itself.

Since construction, KCA has been involved in seven different expansion projects to increase solution flow capacity in the CIC circuit and the pumping capacity in the existing and new heap leach areas.  Since these improvements, the capacity of the ADR plant has been increased to nearly 8000 m3/hr.
