Grade Control, together with operational management and mine planning ensures that the qualities of the blocks planned for mining and the material being mined meet the stringent process requirements of the refinery, in terms of zinc grade, gangue acid consumption and
Grade control drilling is done by drilling out a sample and analysing it. Though this sounds easy, the process is not that simple. Though this sounds easy, the process is not that simple. Grade control is the final step in the process before the mining can be done.
The AccuGrade GPS Grade Control System is a high technology machine control and guidance system that allows dozer operators to grade with increased accuracy, without the need for survey stakes. Digital design data, in-cab operator guidance features and automatic blade controls help the

Abstract. For a mining operation, minimizing misclassification of ore and waste during grade control is of critical importance. This paper reviews grade control procedures for classifying ore and waste that are based on estimation and conditional simulation approaches.
A grade control model is generated in minutes via an automated specification-driven process. the grade control model can be reconciled against the exploration block model to generate: > Accurate tonnage, grade and ounces > 4.Accurate reserves reports > profit information
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.

The grade control data must be available in time to inform and be integrated into the mining plan – if it does not do that, it is too late. In practical terms, the answer will relate to the vertical rate of advance of mining, overall pit geometry and the grade control-mine planning cycle time.
