    Zald var is an open-pit, heap-leach copper mine which produces copper cathodes using the solvent extraction and electrowinning (SX-EW) process. Pure cathode copper is produced by three stages of crushing and stacking of ore, followed by heap leaching and bacterial activity to remove the copper from the ore into solution.

    An important part of any heap leach circuit is the agglomeration drum, also called heap leach drum or Agglomerator. Materials like copper ore and gold ore benefit from the use of agglomeration prior to stacking and leaching the ore to extract the mineral. The main duty of the drum is to roll the fines material after it has been crushed to promote a uniform particle size to create and mix in ...
