Annual Maintenance of Leaching Tanks - ASDR Canada

Annual Maintenance of Leaching Tanks

Mandate and Goals

ASDR is mandated to perform major maintenance work on the leaching tank agitators. The mandate includes the wear analysis on various tank components as well as the replacement of liners and mechanical components.

Challenges and Issues

  • Compliance with cyanidation standards 
  • Performing detailed risk analyses as each movement must be carefully planned since work is executed from a crane-suspended  basket
  • Carrying out work outdoors, which is often impacted by severe weather conditions
  • Planning efficient shutdowns and start-ups of equipment to maximize productivity

Solutions and Achievements

  • ASDR leveraged its design and manufacturing capabilities to produce project-specific tools to work in a quicker, safer and more ergonomic manner 
  • Implementation of safe work methods to increase productivity 
  • Active participation in the development and improvement of maintenance processes with the client
  • Client LaRonde Mine and Canadian Malartic Mine
  • Services provided Leaching Tank Maintenance
  • Place Abitibi-Témiscamingue, Quebec
