Grade control aims to deliver adequately defined tonnes of ore to the process plant. The foundation of any grade control programme is collecting high-quality samples within a geological context. The requirement for quality samples has long been recognised, in that these should be representative and fit-for-purpose. Correct application of the Theory of Sampling reduces sampling errors across ...

When It Comes to Gold Mining Check First!

Apr 20, 2021 For underground mining, geologists perform ore grade control to figure out where the most profitable ore bodies are, in terms of location and mineral concentration variability. There is a need to check first as ore deposits are inconsistent in nature, having high concentrations of metals in one area but much lower concentrations in others.


Four STEINERT KSS LXT sorting machines, each with a working width of 2 metres, were used to recover zinc, lead and silver ore residues from tailings. Material between 12 and 35 mm with very low ore concentrations could be converted by the sorting process into a product with substantially greater concentrations that could then be viably processed.

Grade Control SpringerLink

Abstract. In some mining operations, one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical types.
