CARACTERIZAÇÃO DE PRÉ-CONCENTRADO DO REJEITO DE SCHEELITA DA MINA BREJUÍ EM CONCENTRADOR CENTRÍFUGO

Abstract

Com o intuito de estudar alternativas de aproveitamento de scheelita contida nos rejeitos oriundos dos processos de beneficiamento de forma otimizada, torna-se necessária a caracterização desse material obtido da Mina Brejuí em Currais Novos/RN, que foi pré-concentrado em concentrador FALCON SB- 40. O resultado da análise por DRX indica que associado ao rejeito de scheelita tem-se a calcita, quartzo, albita, anortita e biotita. As análises de FRX revelam um aumento do percentual de WO3 no pré-concentrado e altos teores de CaO e SiO2, indicando uma grande concentração de calcita e quartzo. Em relação ao tamanho de partícula, o rejeito apresenta predominância de partículas finas. A identificação e quantificação das fases minerais bem como a classificação e análise de sua composição gera informações relevantes aos processamentos minero-metalúrgicos e abre alternativas para o aproveitamento do mineral de interesse. PALAVRAS-CHAVE: Scheelita, Rejeito, Caracterização, Concentrador centrífugo.
