O estado da arte dos depósitos cromitíferos do Vale do Jucurici (Ipueira-Medrado): conceitos sobre modelagem geológica 3D, de geoestatística e integração dados

Abstract

The industrial sector of mining is characterized as one of the fundamental economic activities, which provide the basis and foundation for numerous other sectors in the country, such as agriculture, civil construction, the ceramic and processing industries for the production of metal alloys (GONZALO, 2015). Currently, according to the National Mining Agency (ANM), Brazil has 53 active research and mining titles for 37 metallic substances, where 80% of the Brazilian GDP related to mineral production came from this class, which among them is the chrome. Through technical-scientific development, mineral research began to gain new techniques and deterministic methods, allowing the representation of mineral deposits in digital media (BITAR, 2000). More and more technological and precise methods become part of the scope of geotechnologies in scientific development, such as geophysical acquisitions, or even through remote sensors, as well as data rendering for data projection in different dimensions. Due to this technological evolution, several methods started to gain participation in the characterization of mineral deposits, which consequently led to the development of geostatistics as a fundamental method in the determination of deposit cubage stages and structuring of digital models (FERANDES, 2009). The Medrado mine, together with Ipueira, constitutes two of the main chrome mines explored by Companhia Ferro-ligas da Bahia (Ferbasa) and is among the largest deposits of this type of commodity in Latin America. The grouping of information on chromitiferous deposits is of great importance to support further research in the region in this type of deposit.
