Ore mining fundamentally depends on the definition of its tenor and volume, something extremely complex in disseminated mineralization, as case certain types deposits gold sulfites. This article proposes use electrical tomography for a geophysical signature terms resistivity chargeability, an outcrop mineralized quartz lode at end inactive mine. One targets was to analyze continuity body, occurrence new outcrops applicability method auxiliary tool mineral extraction. Three parallel lines...

<title>Abstract</title> This study utilizes gamma-ray spectrometry to identify source areas of gold recognized in geo-chemical prospecting work stream sediments. The local geological context is represented by the Passo Feio Metamorphic Complex, which contains deposits possibly hosted quartz veins concordant with metamorphic foliation, composed quartzites, schists, and amphibolites. followed sequence: reconnaissance, drone survey, spectrometric acquisition. Field reconnaissance indicated an...

The dumps are areas of final disposal solid wastes directly into the soil, with no technical criteria or collecting systems gases liquids. A large part Brazilian municipalities have used this extreme damaging alternative to environment up year 2010, when a federal law made compulsory installation sanitary landfills. However, parts were simply abandoned, although some eventually go through treatment after assessments state environmental agencies. This work presents results geophysical...

The discovery of new mineral resources involves various research techniques through direct and indirect studies. geophysical methods are important tools in the detection deep deposits because they use contrast between physical properties hosting rocks mineralized zone. In this sense, electrical widely used prospecting sulfide deposits. This work presents discusses results application Induced Polarization method investigation a tin occurrence associated with greisen, located on western border...

This study presents the use of terrestrial magnetometry method in characterization a metamorphic and chromium-mineralized ultramafic body São Sepé region (RS). Several serpentinite exposures were recognized area, characterized by very evident schistosity marked amphiboles micas. The most preserved rocks are gray to dark green color, silky touch with folds variable fracturing. chromite present serpentinites is associated magnetite, occurs form small lenses. 1677 reading lines made...
