Since September 2015 Escondida has been operating two open pits (Escondida and Escondida Norte), and has the capability to use its three concentrators (the 130kt/d ore Laguna Seca and the 100kt/d Los Colorados and the 152kt/d ore OGP1). However, the milling capacity is constrained by the availability of water. Additionally Escondida operates two leaching pads including a 48kt/d oxide ore pad, a 220kt/d ROM sulphide ore for leaching, and a 330kt/a cathode EW plant. The EW plant operates the 120kt/a tankhouse No. 1 which is dedicated to the oxide PLS and the 210kt/a tankhouse 2 dedicated to the sulphide PLS. The PLS solution needs to be treated separately to avoid killing of the bacteria of the sulphide PLS solution. The EW operates with some idle capacity.
