Spence Information

  • General 2015-05-10
    Spence operations include an open pit mine, sulphide leaching and oxide processes, and an SX-EW process. Ore is crushed, agglomerated, and transferred to leach pads at a rate of 50,000 tonnes/day. Sulphide and oxide ores are leached on separate dynamic (on ‚‚‚‚‚‚‚‚– off) pads. Solvent extraction consists of four trains in a series-parallel configuration with extraction stages for both oxide and sulphide Pregnant Leach Solution. Copper is electrowon to produce cathodes at a nominal rate of 200,000 tonnes per year. Cathode is transported to either ports of Antofagasta or Mejillones for shipping to customers. Spence employs 670 people directly and 400 indirectly.
