Weir Minerals announces another major order of Enduron HPGR in Gold application with valued Customer IAMGOLD.

An Enduron HPGR with rolls measuring 2.4 m by 2.4 m (length : diameter) will be installed at IAMGOLD's Côté Gold Project. This will be the largest HPGR in Canada and the largest in the world in a gold hard-rock application.

Weir Minerals’ Enduron HPGR unique design is perfectly suited to IAMGOLD’s Côté Gold operations to achieve industry-leading particle size reduction and with the lowest total operating costs.

Enduron HPGR:

  • Is the market-proven HPGR with mechanical design to support efficient and durable skewing thanks to its unique bearing arrangement and control philosophy.
  • Has a unique roll diameter-width ratio that maximizes throughput at the desired product grind.
  • Has self-adjusting cheek plates that provide equal sealing distance as flanges at minimum costs.
  • Is the market leader in large-format, high-tonnage hard-rock HPGR.

Tim Lundquist, HPGR regional sales manager North America stated, “Our Enduron HPGR design will create energy savings of up to 40 percent compared to an equivalent SABC comminution circuit, while also significantly reducing the need for downstream grinding media. This power and grinding media savings will optimize total ownership cost and also account for a significant reduction in carbon emissions.”
