Methodology for a dump design optimization in large-scale open pit mines

In large-scale open pit mines, the mining process is rather complex and often involves different run-of-mine (ROM) ore and waste material treatment downstream. Appropriate areas to place these large amounts of material are limited and their selection and design must serve the environmental factors and economic goals of the long-term mine plans.
