APL key benefits


  • With selected concentrates, APL recovers up to 98% of copper from concentrates in less than 8 hours.
  • APL does not require high pressures, consequently there is no need for expensive autoclaves.
  • The leaching takes place at 95 degrees Celsius - no high temperatures or complex and expensive external heating systems.
  • APL incorporates the standard SX-EW technology stage, which allows the production of 99.99% copper cathodes.
  • Instead of shipping concentrates, the mines can now ship cathodes, thereby drastically reducing transportation costs. ...
