Caracterização Mineralógica e Beneficiamento do Caulim de Prado (BA)

Abstract

Na região de Prado, sul da Bahia, Brasil, ocorre um importante depósito de caulim que tem sido explorado pela Mineração de Caulim Monte Pascoal desde 1992. O caulim destina-se principalmente à indústria do papel e para produção de catalisadores utilizados no craqueamaneto do petróleo. O depósito apresenta dois tipos distintos de minério. O caulim da base da sequência é de origem primária, qualidade superior e destina-se principalmente à indústria do papel. O caulim do topo é de origem sedimentar e de qualidade inferior, baixo grau de cristalinidade e alto teor de ferro e destina-se principalmente à indústria de catalisadores. O caulim foi submetido ao processo separação magnética e tratamento com agente redutor, ditionito de sódio visando elevar o índice de alvura e eliminar as impurezas mineralógicas presentes no caulim. As amostras foram caracterizadas através da difratometria de raios X, microscopia eletrônica de varredura e ressonância paramagnética eletrônica. Os espectros de RPE das amostras de caulim exibem ressonâncias paramagnéticas (g = 4,9 e 4,2) atribuídas ao Fe3+ em sítios de simetria octaedral na estrutura da caulinita substituindo o Al3+ e ressonância ferromagnéticas (g = 2,0) associadas a óxidos e/ou hidróxidos de ferro presentes em fases externas a caulinita.
