Abstract

<B>"MéTODO PARA APROVEITAMENTO DE MATéRIAS PRIMAS SECUNDáRIAS CONTENDO FERRO, ZINCO E CHUMBO"<D>. A presente invenção se refere a um MéTODO PARA APROVEITAMENTO DE MATéRIAS PRIMAS SECUNDáRIAS CONTENDO FERRO, ZINCO E CHUMBO, de preferência pós de aciaria, e mais particularmente em um forno cilíndrico giratório equipado para um processo rotativo (Processo Waelz) com emprego de escória alcalina. Com a limitação da parte de portadores de carbono na carga consegue-se de um lado o aumento do saldo de energia do processo rotativo (Processo Waelz) e de outro melhora-se a eficiência de rendimento do forno cilíndrico giratório utilizado. Devido à melhoria na qualidade da escória oriunda de processo rotativo ampliam-se suas possibilidades de aproveitamento.
