Peru is home to some of the largest gold and base metal mines in the world and ACL has provided modular, stick built and mill enclosed laboratories designs, training and laboratory management. Elevations of greater than 10,000' provide ventilation and equipment selection challenges. Large tonnage operations can generate significant numbers of samples demanding efficient high production designs that that generate quality analysis. Huge low grade heap leach gold mines require excessively large test samples in order to ensure mining operations are providing the leach pads with material of economical value. This requires metallurgical test equipment proportioned to the task at hand.
