Operations began in 1996 at this mine in Chile, a porphyry copper deposit with sulfide and oxide mineralization. As the oxide ores approached depletion, a new stacking area was created to process sulfide ores, to be fed by a relocated overland conveyor and mobile tripper.
In support of this transition, TNT designed, supplied and provided on-site construction supervision for the installation of the world’s largest mobile heap leach stacking system (8,550 t/h), surpassing the 7,200 st/h (6,530 t/h) Super Portable® system TNT built at a copper mine in Arizona. This Chilean mine’s Super Portable system, designed by TNT in 2007-08, comprises 23 – 250’ long Super Portables, a 110’ long Horizontal Feed Conveyor, 275’ long Horizontal Conveyor, and 190’ / 220’ long Radial Stacker with 30’ telescoping stinger.
TNT’s patented Super Portable® technology allows fully independent movement of each piece of mobile conveying equipment on the stacking pad. During 2011, this mine commenced production from its sulfide ores using this system.
