A mathematical programming model for optimal cut-off grade policy in open pit mining operations with multiple processing streams

Cut-off grade classifies the available supply of ore (valuable) and waste material within a mineralised deposit. Given the mining, processing and refining limitations of a mining operation, an optimal cut-off grade policy ensures that the flow of ore from the mine to the processing and refining faci...
