About the Book

Devido à extração intensiva de minérios de manganês de alta qualidade durante muito tempo, deixando para trás os minérios de baixa qualidade, tornou-se necessária a utilização destes últimos. Existem várias diferenças físico-químicas entre os componentes dos minérios de manganês, que podem ser utilizadas para o enriquecimento de manganês. Em particular, os abundantes minérios de manganês de baixo grau, que contêm óxido de ferro, podem ser melhorados por pré-redução e separação magnética. Neste livro, o minério de manganês ferruginoso de baixo teor foi pré-reduzido por coque de brisa como fonte de carbono na forma de briquetes e pellets, a redução ocorreu na faixa de temperatura de 600 -950°C . No estudo da cinética de redução, o modelo mais satisfatório foi feito para tomar o declive da região linear inicial da curva de redução fraccionada vs. tempo como uma medida da constante de velocidade (k). Os gráficos de k vs. 1/T são linhas rectas a partir das quais se calcula a energia de ativação.
