Accurate modelling improves long term strategic planning

Features

To maintain long term profitability and mitigate risk it is important to understand how variability in the deposit will affect the operation. Achieving this goal requires an understanding of how the process behaves for different ore types and the distribution of ore types throughout the ore body.

Integrating the disciplines of geology, mining and metallurgy, our geometallurgical modelling solution helps you to develop proactive operating strategies from mine to plant as a function of ore variability.

Effective geometallurgical modelling requires good quality ore characterization data and knowledge of how these properties affect process performance. At the heart of our service, GeoMetso™ provides an automated link between the ore source and plant performance. As a result, the predictive models and geotechnical block model are automatically updated in real time.

Parcels of ore are tracked continuously from the mine into the process using SmartTag™ technology and the associated plant performance data is collected from the control system. This data is automatically compared with model predictions and updated in the block model in real time. As a result, the block model is continuously populated and refined with actual plant data, eliminating the need for further expensive ore characterization tests. Additionally, it improves the accuracy and predictive abilities of geometallurgical modelling.

Benefits

  • Improve reconciliation and strategic long term mine planning
  • Accurately predict future performance
  • Determine optimum revenue cut-off relationship
  • Optimize blending and ore delivery strategies
  • Predict the need for capital equipment purchases well in advance
  • Provide advance notice of ore types for adjustment of operating conditions
  1. Ore domains are defined based on preliminary ore characterization tests.
  2. Site-specific predictive geometallurgical models are developed for each stage (blasting, comminution, separation)
  3. SmartTags™ are used to continuously track ores from the mine through the process, and actual plant performance data (throughput, recovery, grade) for that ore is collected from the plant control system.
  4. The actual plant data is automatically compared with model predictions and updated in the block model using the SmartTagTM software in real time
  5. The block model is continuously updated and refined with actual plant data to improve the accuracy and predictive abilities of geometallurgical modelling
