Sampling Theory, Sampling Practices, and Their Economic Impact

October 09, 2017 - October 13, 2017
Golden, USA

Colorado School of Mines, 924 16th Street

What you will learn

  • You will become familiar with the nine different kinds of sampling errors, how they take place, and how to minimize them; most people can list only two!
  • You will become familiar with sampling correctness, so you can eliminate or reject sampling systems offered to you that will never perform a satisfactory job.
  • You will become familiar with necessary tests to be performed at mines and plants to optimize all your sampling protocols.
  • You will be in a position to select appropriate Data Quality Objectives for operating parameters, which are worth continuous monitoring, to minimize your operating cost.
  • You will better appreciate the value of existing chronological data that allow you to better control any process. This data has great value for management, who should use them to identify structural problems leading to unnecessary financial losses.
  • Variography is the key to identify the various sources of variability affecting routine chronological data. You will discover the power of Chronostatistics.
  • Using existing data, variability from sampling and measurement must be clearly separated from process trends and process cycles. Unless this is well done, continuous process improvement will remain elusive.
  • The careful use of the Moving Average and especially its auxiliary functions can greatly help you to minimize the effect of poor sampling and measurement precision.
  • The Relative Difference Plots can show, in an unambiguous way, the presence of conditional biases from sampling and from laboratories.
  • You will finally realize the weakness of today's standards on sampling: They are obsolete and not in line with the Sampling Theory.
  • You will be updated on the new developments in the world of sampling that were exposed during the first World Conference on Sampling and Blending held in Demark in 2003, and the second WCSB held in Australia in 2005.
  • Workshop with software included in progressing lectures.
