Pesquisa mineral e reavaliação da reserva de granito ornamental no Córrego Água Preta, município Nova Venécia, estado do Espírito Santo

Abstract

In Espírito Santo state, one of the segments more profitable is the ornamental stones. The state is located in a strategic geographic position and it is composed by an infrastructure that serves this market, such as port and railroad, proximity to major centers of the country, tax incentives, labor supply, spontaneous agglomeration of companies of the sector, among others. This paper aims to analyze the feasibility of extracting the ore from a quarry in the municipality of Nova Venécia / ES, a geological and structural mapping, macroscopic and microscopic petrography and the technological characterization of the rock are fundamental factors for the recognition and understanding of the ore, and thus judging whether the rock serves the consumer market, has the volume and quality required for its use in the coating industry and / or ornament. This study, to recognize the área, an air making was executed using a drone, facilitating the mapping and enabling important digital modeling for the understanding of the area and content of found. Comparing the data available to the company with the data performed in this survey, it is noticeable that there is a data volume above needs such as those of the company where the ore is located advanced stage of fracturing, it is not possible to size blocks and plates for its commercialization. This situation becomes this ore unfeasible, both for its beneficiation and for its use in the coating industry and civil construction project.
