Abstract

Determination and selection of optimum cut-off grade in case of metalliferous deposits is a very important aspect of mine designing process, which is one of the most challenging problem for surface mining operation and production planning. The cut-off grade of a metalliferous deposit is dynamic in nature thus dynamic programming approach may be considered as one of the suitable methods for solving the cut-off grade determination problems. This paper analyzes an open pit copper mine project considering fixed mine production annually and having no other capacity constraints with respect to milling and refining. A computer tool cut-off grade predictor (COGP) had also been developed based on the dynamic programming algorithm, which iterates through the range of grades to determine the optimum value of the cut-off grade for achieving the maximum value of net present value (NPV). The computer tool was built with the help of Visual Basic 2010 programming language. The software package comprises 3 modules – Input data module, Output result module and Result graphical module.
