Global Insights from Canada – CMP 2021 Online Conference Highlights

In news from Canada, CEEC commends the successful online delivery of the annual Canadian Mineral Processors’ Conference in Canada, January 2021, a first for the team.

Industry and research leaders and practitioners presented on the following topics:

  • Quebec Iron Ore’s Bloom Lake iron ore mine - the significant plant flowsheet changes helping the restart to achieve new production records and improved recovery
  • Agnico Eagle’s LaRonde gold and polymetallic mine and concentrator
  • Glencore Sudbury Integrated Nickel Operations’ Strathcona mill with flexible flow sheet to enable multiple feed processing
  • St-Barbara Limited Atlantic Gold’s Touquoy gold mine commissioning and ramp up reaching high mill availability and future expansion plans, and rapid implementation of other projects
  • Hudbay Minerals Inc.’s Snow Lake concentrator and mill, processing ore from the Lalor Mine
  • Presentations on nickel recovery from slimes streams, lifter wear prediction, geometallurgy, preventative maintenance and remote monitoring
  • The growth in important comminution machine learning techniques, including evolution of data-based, fault detection and image classification techniques, gaps, and future research needs
  • Development and process design of The First Cobalt Refinery in Ontario, aiming to produce Canada domestic EV battery-grade cobalt sulphate
  • Energy usage and carbon dioxide emissions from comminution
  • A roadmap for evaluating coarse particle flotation for projects - process to consider options, including screening of ore candidates, lab, and pilot test, and applying results to flowsheet design

Masterclasses were held on:

  • De-constraining underperforming circuits, on identifying the issues, and a systematic approach for optimization across asset disciplines to achieve productivity goals
  • Mill liner selection and optimization to reduce relining and enhance productivity, including what to measure, how to account for liner mass loss, and advanced liner design for productivity
  • Brownfield plant optimization economics, including economic levers for operating plants and a live modelling exercise to assess scenarios, including water, downtime, and productivity impacts

Panels were held on:

  • The Future of the CMP - Have Recent Virtual Trends Changed Conferences Forever?
  • The Co-Evolution of Operators and Suppliers
  • The Most Commonly Encountered Implementation Questions from Real-World Ore Sorting Projects

Student posters included work on gravity separation, carbon capture and storage in ultramafic ore processing and MIBC dosage in flotation.
