This paper addresses the optimization of mineral supply chain operations under metal and material type uncertainties. A mathematical model to simultaneously ...
référence BibTeXOptimal mining rates revisited: Managing mining equipment and geological risk at a given mine setup
This paper presents a mixed integer programming formulation dealing with the effective minimisation of risk incurred when optimizing mining production rates ...
référence BibTeXMultiple-point simulation of Olympic Dam copper deposit, Australia, using wavelet analysis
Traditional geostatistical simulation methods assume that the first two order statistics are sufficient to model mineral deposits. However, these methods are...
référence BibTeX
Modeling and assessing spatial uncertainty of mineral deposits is critical for capital investments in mining projects. However, traditional approaches for mo...
référence BibTeXStochastic long-term production scheduling of the LabMag iron ore deposit in Labrador, Canada
A long-term production schedule for the LabMag iron ore deposit in northern Québec, Canada is derived using stochastic integer programming. The optimization ...
