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 ...

Geological modelling is a key step prior to grade estimation in a mineral deposit and consists of a deterministic partitioning of the deposit into sub-domains called 'geological units', each with relatively homogeneous ...

El Decreto-Ley No. 301, de 9 de octubre de 2012, crea el Ministerio de Energía y Minas, encargado de proponer y, una vez aprobadas, dirigir y controlar las políticas del Estado y del Gobierno en los sectores energético, ...

Core logging is the geological study, recording and classification of petrophysical attributes of drill hole samples, such as lithology, alteration or mineralogical assemblage. The geological logging is qualitative and ...

An accurate definition of geological domains that differentiate the types of mineralogy, alteration and lithology is a critical step in mineral resources and ore reserves evaluation. Deterministic models define just one ...

© 2018 Geological Society of America.Determination of the sediment fill geometry and structure of basins along the western flank of the Central Andes is crucial for understanding the regional tectonic evolution and the ...

Mineral resource evaluation requires defining geological domains that differentiate the types of mineralogy, alteration and lithology. Usual practice is to consider the domain boundaries as hard, i.e. data from across the ...

The uncertainty in the recoverable tonnages and grades in a mineral deposit is a key factor in the decision-making process of a mining project. Currently, the most prevalent approach to model the uncertainty in the spatial ...

This chapter brings a brief nuclear legislation scenario in force in Brazil and the competences of several bodies which control and regulate the nuclear industry. It describes the various roles of such bodies and the ...
