For example, in Chile, the total SX/EW copper produced reached 1400 thousand tons during 1999, representing almost one half of the total electrolytic copper produced (Pezoa, 1999). This paper is focused on the control practices and trends in LX–SX–EW copper plants. Typically, the process starts with the crushing and grinding of ore.
