Abstract

In recent years several mine researchers have studied the OPTIMIZATION of CUTOFF GRADE with purpose of maximizing Net present Value (NPV). The best and popular one is Lane algorithm. Based upon Lane algorithm it is possible to calculate optimum CUTOFF GRADE with regard to mine, mill, and refinery capacities for single metal deposits with variable grade. In this study iterated grid search (IGS) method was used to calculate optimum CUTOFF GRADEs of multiple metal deposits for the same conditions as Lane assumed in single metal deposits. Based on this method first, one grid of metal grades was defined and objective function of NODEs of this grid was evaluated then NODE wit highest amount of objective function was determined and one new grid around this NODE was created. To make calculation more accuracy, the smallest size of grid around the optimum NODE was chosen and for each NODE of new grade, the amount of objective function and optimum CUTOFF GRADEs were determined. These operations were continues were continued until the optimum CUTOFF GRADEs with high desirable accuracy found.
