Detour lake gold – Magnetic Separation

Location Ontario, Canada
Year of realization 2020
Project type OPEX

The Detour Lake open pit mine produces over 650,000 ounces of gold annually. To achieve this, more than 20 million tons of raw ore must be crushed. To avoid breakdown of various parts of the crushing and refining equipment, it is essential to remove any metal debris that could come from the mine and be transported along with the raw ore. The factory had a magnetic separator for this purpose. However, its effectiveness was considered low.

Reliable and efficient magnetic separation is crucial to prevent equipment breakage

TRINUM completed an audit of the existing facilities and changed the factory configuration:

  • Moving of the magnetic separator after the Apron Feeder
  • Installation of a monorail
  • Installation of a new debris chute
