Optimisation of the grade control procedures at the Yandi iron-ore mine ...

The irregular shapes and highly erratic distribution of the clay pods are a serious challenge for grade control at this mine. Current grade control procedures at the Yandi open pit are based on sampling 10 m deep blast holes on a 6 × 6 m grid. An alternative approach was considered of using reverse circulation (RC) holes.

Using Portable XRF Analysis for Ore Grade Control in Mining

Ore deposits are inconsistent in nature, having high concentrations of metals in one area but much lower concentrations in others. Mining geologists perform ore grade control in underground mining operations to figure out where the most profitable ore bodies are, in terms of location and mineral concentration variability. By performing ore grade control, mining operators are also reducing risk ...

The variability samples were chosen so that the ore grade proportions in the 150 samples matched the histogram of the grade proportions of the orebody. That means that if 10% of the orebody is 1%-2%Cu, then 15 samples (10%) where 1%-2%Cu, 23% of the orebody was 0.75%-1%Cu, then 35 samples (23%) had that grade range, and so on.

Traditionally, grade control of iron ores has relied on elemental analysis of sampled materials such as blast cone drill cuttings. This analysis provides a standard elemental suite (Fe, SiO 2, Al 2 O 3, P, Mn, S, MgO, CaO and TiO 2 along with loss on ignition) that is used in grade control to assign mined material as grade blocks to high grade, low grade or waste destinations.
