Eriez is proud to offer an expanded Central Test Lab (CTL) facility at our Wager Road facility. Offering sample testing with flotation, magnetic and hydraulic separation and filtration equipment, the CTL has a highly qualified staff with years of expertise along with a broad range of application experience. The staff includes engineers with advanced degrees at both the master’s and doctoral levels along with field experience that is unmatched in the industry.

With more than 15,000 square feet of dedicated laboratory space and an array of lab and pilot equipment, Eriez has the tools to test and provide detailed process analysis and state-of-the-art solutions for nearly any application.

Eriez provides both on-site evaluations and in-house lab services. Our on-site testing services provide quantitative data generated on a demonstration scale in the plant environment. And, with an experienced team of process engineers, Eriez also excels at improving plat performance by conducting thorough circuit evaluations, determining optimum operating conditions, and finding solutions for common problem.

In-house, Eriez possesses laboratory equipment ranging from grinding mills to bench-top and column flotation cells, and complex plant circuitry can even be tested and simulated, rather than the traditional method of independent staged testing.


Eriez’ battery of test equipment includes:

  • Single and multi-stage column flotation circuits
  • Bench top flotation cells
  • Pilot-scale columns
  • Lab- and pilot-scale HydroFloat Separators
  • Lab- and pilot-scale CrossFlow Separators
  • Grinding equipment (cone, ball, and rod mills)
  • XRF analytical capabilitiesPilot Scale Testing


Testing and Analysis capabilities includes:

  • Bench-top batch testing
  • Batch milling (ball, rod)
  • Continuous milling (ball, rod)
  • Steady-state column flotation testing
  • High and low gradient magnetic separation
