Abstract
The cutoff grade of valuable components delimits the complex ore reserves suitable for efficient mining. The cutoff grade optimization is conducted to maximize the net present value of products in mining projects. The investigations were realized by using the equivalent grade method, iterated grid search method, genetic algorithm, and golden section search. The software presented ensures the calculation of the optimal production with melting considered and the cutoff grades over the life of mine.
