Abstract

AS CROSTAS DE FERRO E MANGANêS (CROSTAS FEMN) SãO RECURSOS MINERAIS ENCONTRADOS EM ALTO MAR E QUE ACUMULAM ALTAS CONCENTRAçõES DE ELEMENTOS QUíMICOS NECESSáRIOS à TRANSIçãO ENERGéTICA. NESTE ESTUDO, PROPõE-SE A CARACTERIZAçãO TECNOLóGICA DE AMOSTRAS DE CROSTAS FEMN, COLETADAS NA ELEVAçãO DO RIO GRANDE (EGR), EMPREGANDO TéCNICAS DE ESPECTROSCOPIA VIBRACIONAL. FORAM UTILIZADAS PARA A TAL A ESPECTROSCOPIA VIBRACIONAL NA REGIãO DO INFRAVERMELHO (FTIR) E A ESPECTROSCOPIA RAMAN. OS RESULTADOS OBTIDOS POR FTIR INDICAM O POTENCIAL DA TéCNICA PARA QUALIFICAR AMOSTRAS QUE CONTENHAM DIFERENTES QUANTIDADES DE FOSFATO E DE CARBONATO, UMA MANEIRA INDIRETA DE IDENTIFICAR CAMADAS DE CROSTAS ENRIQUECIDAS EM MINERAIS CRíTICOS. OS ESPECTROS RAMAN REITERAM A COMPLEXIDADE DE CARACTERIZAçãO DAS AMOSTRAS, MAS PERMITEM IDENTIFICAR MINERAIS DE INTERESSE NAS AMOSTRAS, TAIS QUAIS ASBOLANO E LITIOFORITA. TAIS RESULTADOS SE MOSTRAM IMPORTANTES DAR SUBSíDIOS à QUALIFICAçãO DAS AMOSTRAS EM ESTUDOS EM CAMPO E à FUTUROS TRABALHOS DE PROSPECçãO.

 

FERROMANGANESE CRUSTS (FEMN CRUSTS) ARE MINERAL DEPOSITS LOCATED AT DEEP-SEA WHICH CONTAINS HIGH CONTENTS OF CHEMICAL ELEMENTS PIVOTAL TO ENERGY TRANSITION. IN THIS STUDY, IT IS PROPOSED THE TECHNOLOGICAL CHARACTERIZATION OF FEMN CRUSTS SAMPLES COLLECTED AT RIO GRANDE RISE BY USING VIBRATIONAL SPECTROSCOPY TECHNIQUES. TO ACHIEVE THIS PURPOSE, VIBRATIONAL SPECTROSCOPY AT INFRARED REGION (FTIR) AND RAMAN SPECTROSCOPY WERE EMPLOYED. FTIR RESULTS INDICATE THE POTENTIAL FOR ITS USE IN SAMPLES QUALIFICATION REGARDING PHOSPHATE AND CARBONATE CONTENT. THIS IS AN INDIRECT IDENTIFICATION OF CRUSTS LAYERS ENRICHED IN CRITICAL MINERALS. RAMAN SPECTRA EVIDENCE THE COMPLEXITY TO CHARACTERIZE THE SAMPLES, BUT ALSO ALLOWS THE IDENTIFICATION OF INTERESTING MINERALS, SUCH AS ASBOLANE AND LITHIOPHORITE. THESE RESULTS AS IMPORTANT TO SUBSIDE SAMPLES QUALIFICATION AND FURTHER IN-FIELD STUDIES AND PROSPECTING WORK.
