Estimation of Open Cut Mining Recovery and Mining …
Mine to mill is a process for optimisation of mining and processing recovery and costs. The choice of either selective mining or bulk mining techniques is a major consideration, however evaluations rarely undertake careful consideration of Mining Recovery and Mining Dilution in the context of mine to mill optimisation.
