Abstract

A MINERAçãO URBANA, ENQUANTO UMA SOLUçãO EFICIENTE PARA A RECUPERAçãO DE VALOR A PARTIR DE ESTOQUES ANTROPOGêNICOS, PODE SER VIABILIZADA A PARTIR DE PROCESSOS TECNOLóGICOS E CONTRIBUIR PARA O SUPRIMENTO DE MINERAIS CRíTICOS E ESTRATéGICOS. ENQUANTO A MINERAçãO TRADICIONAL UTILIZA PROCESSOS PARA O MAPEAMENTO, IDENTIFICAçãO, CARACTERIZAçãO E CONCENTRAçãO DAS FRAçõES MINERAIS DE INTERESSE, A MINERAçãO URBANA UTILIZA PROCESSOS SEMELHANTES PARA A RECUPERAçãO DE RECURSOS A PARTIR DE FONTES SECUNDáRIAS, CONSUMINDO MENOS ENERGIA E MATERIAIS. ESTE ESTUDO TEM COMO OBJETIVO ANALISAR DE FORMA COMPARATIVA A MINERAçãO TRADICIONAL E A MINERAçãO URBANA, CONSIDERANDO O POTENCIAL DE RECUPERAçãO DE MINERAIS CRíTICOS E ESTRATéGICOS A PARTIR DAS FONTES SECUNDáRIOS. PARA TANTO, A PARTIR DE UM LEVANTAMENTO BIBLIOGRáFICO SOBRE O TEMA FOI REALIZADA A ANáLISE COMPARATIVA DAS ABORDAGENS. OS RESULTADOS SUGEREM QUE A MINERAçãO URBANA NãO SUBSTITUIRá A MINERAçãO TRADICIONAL, MAS CONTRIBUIRá COM A APLICAçãO DOS PRINCíPIOS DA ECONOMIA CIRCULAR POR MEIO DA RECUPERAçãO EFICIENTE DE RECURSOS E MITIGAçãO DOS IMPACTOS NA GESTãO DE RESíDUOS, RESULTANDO NA REDUçãO DA INCERTEZA EM RELAçãO AO FORNECIMENTO DE MINERAIS CRíTICOS E ESTRATéGICOS. O ESTUDO AINDA APONTA PARA O POTENCIAL DE RECUPERAçãO DE MATERIAIS SECUNDáRIOS A PARTIR DA GESTãO DOS RESíDUOS DE EQUIPAMENTOS ELETROELETRôNICOS NO BRASIL.

 

URBAN MINING, AS AN EFFICIENT SOLUTION FOR RECOVERING VALUE FROM ANTHROPOGENIC STOCKS, CAN BE MADE POSSIBLE THROUGH TECHNOLOGICAL PROCESSES AND CONTRIBUTE TO THE SUPPLY OF CRITICAL AND STRATEGIC MINERALS. WHILE TRADITIONAL MINING USES PROCESSES FOR MAPPING, IDENTIFICATION, CHARACTERIZATION AND CONCENTRATION OF MINERAL FRACTIONS OF INTEREST, URBAN MINING USES SIMILAR PROCESSES TO RECOVER MINERALS FROM SECONDARY SOURCES, DEMANDING LESS ENERGY AND MATERIALS. THIS STUDY AIMS TO ANALYZE COMPARATIVELY TRADITIONAL MINING AND URBAN MINING, CONSIDERING THE RECOVERY POTENTIAL OF CRITICAL AND STRATEGIC MINERALS FROM SECONDARY SOURCES. A COMPARATIVE ANALYSIS OF BOTH APPROACHES WAS CARRIED THROUGH THE BIBLIOGRAPHICAL ANALYSIS. THE FINDS SUGGEST THAT URBAN MINING WILL NOT REPLACE TRADITIONAL MINING BUT WILL CONTRIBUTE TO THE APPLICATION OF CIRCULAR ECONOMY PRINCIPLES THROUGH EFFICIENT RESOURCE RECOVERY AND MITIGATION OF IMPACTS ON WASTE MANAGEMENT, RESULTING IN UNCERTAINTY DECREASING REGARDING THE SUPPLYING OF CRITICAL AND STRATEGIC MINERALS. THE STUDY ALSO POINTS TO THE RECOVERY POTENTIAL OF SECONDARY MATERIALS FROM THE MANAGEMENT OF WASTE FROM ELECTRICAL AND ELECTRONIC EQUIPMENT IN BRAZIL.
