Summary

Best practice grade control techniques to deliver best quality ore

Schedule

This 3-day course teaches best practice grade control techniques for open pit and underground operations and how to ensure delivery of the best-quality-ore.

You'll learn to minimise misclassification through best practice grade control and optimal estimation.

Topics

Day 1 - Grade control techniques for open pit & underground mines
Reduce misclassification through best practice grade control

You will learn:

• Best practice grade control sampling and data collection techniques
• The pros and cons of different sampling methods used for grade control
• The importance of good geological mapping
• To understand the concept of misclassification and how to minimise ore loss and dilution
• Good practice ore control processes in open pit and underground mines

Day 2 - Grade control modelling
Minimising misclassification through optimal estimation

You will learn:

• The implications of the SMU on misclassification
• Good practice for estimating the grade of ore blocks in open-pit and underground operations
• Which grade estimation techniques should be used and when
• To optimise your sampling grid for your SMU
• To gain an understanding of how conditional simulation can be used to assess grade risk
• About the use and benefits of geometallurgical modeling for grade control

Day 3  - Mine reconciliation process
Using the reconciliation process to increase profit margins

You will learn:

• How to develop your own Reconciliation Code of Practice
• How to map material movements
• How to analyse components of the reconciliation process for your site, how they relate to each other and the key parameters used for reconciliation (inputs/ outputs)
• To identify causes of inconsistencies & inefficiencies in order to implement improvement processes
• About the various stakeholders in the reconciliation process
• How to provide relevant and concise reconciliation information
• How to unlock value from your reconciliation results for operational improvement
• About best practice reconciliation
