Maleki, Mohammad; Emery, Xavier (Elsevier, 2020)Identification and categorization of geological, geotechnical, or geometallurgical domains is a common practice in the modeling of mineral deposits, in order to account for the controls exerted by categorical variables ...

Maleki, Mohammad; Emery, Xavier; Mery, Nadia (MDPI AG, 2017)Geostatistics offers a set of methods for modeling, predicting, or simulating geological domains in space. In addition of being an input of some of these methods, indicator direct and cross-variograms convey valuable ...

Maleki, Mohammad; Emery, Xavier (Elsevier, 2017)In mineral resources evaluation, the joint simulation of a quantitative variable, such as a metal grade, and a categorical variable, such as a rock type, is challenging when one wants to reproduce spatial trends of the ...

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 ...

Maleki, Mohammad; Jélvez Montenegro, Enrique; Emery, Xavier; Morales Varela, Nelson (MDPI, 2020)Production planning decisions in the mining industry are affected by geological, geometallurgical, economic and operational information. However, the traditional approach to address this problem often relies on simplified ...
