Pit Optimization – How I View ItOne of the first steps in open pit mine design is the completion of a pit optimization analysis. Pit optimisation is used to define the most profitable pit shell or nested pit shells for a given set of economic parameters. The economic parameters generally include the metal prices process recoveries and operating costs.
Enterprise Optimization Case Study: PanAust’s Inca de OroMining Cost Model The mining cost model used in PanAust’s pit optimization was based on a flat $/tonne base cost for material mined and an incremental $/tonne depth cost.
