Iron Ore Grade Control for Flitch Mining – An

flitch sampling techniques where: flitch positions were estimated, flitch positions were marked with paint, and; a full cone sample was taken for ‘grade splitting’. Using these data sets multiple grade predictions were produced, then analysed using Half Absolute Relative Difference (HARD) statistical analysis.

Sample Truncation Strategies for Outlier Removal in ...

The presence of outliers in geochemical data can impact the accuracy of grade models and influence the interpretation of mine assay data. Removal of outliers is therefore an important consideration in grade estimation work. This paper presents two sample truncation strategies which have been devised to reject outliers in multivariate geochemical data.
