Improved grade control in open pit mines
Grade control in hard-rock open pit mining is the process of determining the destination for the mined material. Numerical studies are undertaken to show how grade control can be improved, that is, less ore sent to the waste dump and less waste sent to the mill. The improvements in four aspects of grade control are proposed: (1) …

Quantification of sampling uncertainties at grade …
Grade control sampling assay data is used routinely in conjunction with the geology of the ore to assign a destination for the ore (either to a stockpile or to the mill), based on its grade classification for the platinum mine. The classification of the grade for a particular mining block is made using four key elements (4E).

These uncertainties are then integrated into decision-making in the mine planning process. Closely spaced grade control data are used to create a training image. This training image, together with sparsely spaced samples from extension areas, are used to simulate grade in these areas with more confidence than traditional methods.
