    • Geostatistical modeling of the geological uncertainty in an iron ore deposit 

      Mery Guerrero, Nadia Macarena; Emery, Xavier; Cáceres Saavedra, Alejandro; Ribeiro, Diniz; Cunha, Evandro (Elsevier, 2017)
      This paper addresses the problem of quantifying the joint uncertainty in the grades of elements of interest (iron, silica, manganese, phosphorus and alumina), loss on ignition, granulometry and rock types in an iron ore ...
    • Quantifying the uncertainty in the spatial layout of rock type domains in an iron ore deposit 

      Maleki, Mohammad; Emery, Xavier; Cáceres Saavedra, Alejandro; Ribeiro, Diniz; Cunha, Evandro (Springer, 2016)
      This work addresses the problem of delineating the spatial layout of ten rock type domains in an iron ore body and of assessing the uncertainty in the domain boundaries. A stochastic approach is proposed to this end, based ...
