Grade Tonnage Curve In Mining

In the mining industry, from the geology and mine planning areas to management, the grade tonnage curve has been applied in economic and financial analysis probably being one of the most important tools used in determining the volume and grade of material in face of variations of the cut-off grade. The grade tonnage curve is usually calculated with the in-situ resources or reserves and shows

Sep 22, 2020 In this tip of the month, we will see how to insert a statistics report and generate a grade- tonnage curve for a block model. This is really useful to quickly analyze the properties of each grade value and to determine the optimal point of obtaining the maximum grade without decreasing the tonnage

Dec 21, 2017 The grade–tonnage curve shows the importance of incorporating both volume and grade uncertainty in resource modeling. The sensitivity analysis results show that the studied mine is highly sensitive to the servosystem value, and careful selection of this parameter is required for robust resource modeling

Eventually, a post-processing based on convex analysis was implemented to characterize the grade-tonnage curve relationships attainable under certain mining hypotheses (minimum average manganese grade, minimum width mining cavities). The Convex Analysis functionality is a module of Isatis software, developed by Geovariances, and is designed

The sensitivity analysis applied to the grade-tonnage relationship in mining projects is a recognized stage in all existing quality standards. However, once presented, the results are hardly commented on or criticized. This study analyzes more than 50 projects grouped by copper and gold metallogenetic models which find their own characteristics

An application of sequential Gaussian fractal conditional simulation is presented, using actual sparse, irregularly spaced open cut gold data, to predict the grade tonnage curve associated with a single mining bench. It is shown that this constitutes an improvement over the prediction of the grade tonnage curves obtained via standard sequential Gaussian simulation and median indicator
