Portovelo Mill


The Portovelo (formerly known as the 'Zaruma' mill) processing plant (a conventional crush, mill, leach, Carbon-in-Pulp (CIP), elution and electrowinning circuit) is a well established processing plant with a nameplate capacity of 2,000 tpd making it the largest processing plant currently operating in Ecuador (September 2017).

Depending on head grade, up to approximately 25% of the gold can be taken out of circuit via the gravity concentration system. There are other processing flowsheet options available which this project could embark upon to further increase both throughput and precious metal recoveries (adding increased throughput capacity, for example), such as a floatation circuit for increased recovery of silver and possibly other base metals.

Key Highlights

  • Nameplate capacity of 2,000 tonnes per day (tpd).
  • Currently operating at 750 tpd with one ball mill.
  • Located 150km from DGF in Portovelo, Ecuador.
  • Replacement value of minimum USD $30M.
  • Largest CIP mill currently operating in Ecuador.
  • All CGLD material processed at Portovelo plant.
