Challenges

  • ArcelorMittal wanted to increase the iron-ore handling and shipping capacity at its Port Cartier operation from 16 million tons per annum (Mtpa) to 24 Mtpa.
  • The ore-handling equipment was to be debottlenecked and the flexibility of the system increased by adding a new stacker-reclaimer to help store, reclaim, and ship iron-ore concentrate or pellet-plant feed at a rate of 8,000 tons per hour (tph).
  • The plant had to be fully operational during the execution phase.
  • A new ship loader was to be installed as back-up to the existing one.

Solutions

  • The existing conveyor route was modified by constructing two new drive houses to add flexibility.
  • The existing 2,000 tph stacker-reclaimer and associated conveyor were dismantled and replaced with an 8,000 tph stacker-reclaimer and a 1,700-foot-long, 72-inch-wide feed-and-reclaim conveyor.
  • A second ship loader, capable of handling 8,000 tph of iron ore or iron pellet, was added to the existing wharf.
  • The ship loader feed conveyor was also upgraded by replacing the drive system and pulleys.

Highlights

  • The execution strategy minimized the impact on production, keeping the plant fully operational during that phase of the project.
  • By coordinating with the maintenance and operation departments and other ongoing projects at the site, smooth execution was strengthened.
  • The assembly of the stacker-reclaimer was done off-site at Belle Dune, New Brunswick, Canada, and the partially assembled equipment was transported and tested at site.
  • The ship loader was assembled and partially tested in Germany, transported to Port Cartier, and off-loaded on the existing rails.
