El Limon Upgrade Project

Americas, Nicaragua, South America

El Limon is located in northwestern Nicaragua, approximately 100 kilometres north-west of the country’s capital, Managua. It is a historic mine, in operation as an underground and open pit mine since 1941.

When B2Gold assumed ownership of El Limon in 2009, the mine was operating with an aged mill and mining equipment and the company embarked on a programme of exploration and investment to renew the production fleet, the process facility and the mine infrastructure.

Lycopodium provided detailed engineering services relating to an upgrade of the comminution circuit at the existing El Limon process plant. The scope involved upgrading the cyclone classification system of the grinding circuit to process 500 ktpa of ore. The upgrade was part of a planned potential future expansion to process 600 ktpa through a tertiary grinding circuit. The equipment was sized, and the design undertaken, to accommodate the potential future expansion.

Lycopodium’s scope of services included:

  • Project Management
  • Process Engineering
  • Mechanical Engineering, Civil / Structural Engineering and Electrical / Instrumentation Engineering
