Understanding the impacts of poor sampling, how to optimise the frequency size and the nature of the sample, and quantifying the errors associated with your samples is among the most important information you must have.
In this 1-day course we examine the two principal fields of sampling – theory and practice. Practice of how the sample is taken, delimited, reduced, transported and prepared; and the theory of how to measure the errors associated with our sampling protocols, and to optimise those protocols. The outcomes will be a detailed understanding of what the key issues in sampling are and how to ensure value add in the sampling process.
Course outline:
- Introduction – fundamentals of sampling; precision, accuracy and bias; the relationship between sampling and QAQC; a practical demonstration of sampling issues.
- Understanding the various types of sampling error and how they interact; realise that errors in sampling don’t cancel!
- A thorough review of sampling practice from exploration through to concentrate sampling at the port; sampling horror stories and success stories.
- How to calculate the fundamental sampling error and the three key drivers for sampling error; the FSE and total error; the FSE and the nugget effect.
- Sampling protocols; what are they, how to calculate one, how to analyse and critique one; the objectives of a protocol.
- Sampling throughout the mining/processing/shipping cycle; good and bad samples; understanding sampling for metal balance calculations.
During the course you will:
- Cover the key areas of sampling practice associated with drillholes, broken material and moving sample streams.
- Understand how to take a reliable sample and how to recognise and remedy poor sampling practice in the exploration and mining cycle.
- Appreciate the various errors that contribute to overall sampling error; understand which can be minimised and which can merely be measured.
- Construct and evaluate sampling protocols and learn how to optimise sampling schemes for maximum return on investment.
- Understand the effects of sampling practice in reconciliation and metallurgical balance calculations.
