Description
A process under development at COPPE/UFRJ to rocover vanadium from a titaniferous magnetite type ore from Campo Alegre de Lourdes (Bahia, Brazil), throxgh magnetizing roasting/magnetic concentration/ salt roasting/hot water leaching, is described. The results of the experimental work carried cut up to present are in qualitative agrement with those of othar studies on salt roasting/water leaching of titaniferous magnetites. Is is discussed the existing relationship between the maximum percentags of vanadium extraction in the leaching and the salt roasting conditions. (author)

E descrito um processo em desenvolvimento na COPPE/UFRJ para a extracao de vanadio a partir do minerio ferro-titanifero de venadio de Campo Alegre de Lourdes (Bahia, Brasil), atraves da ustulacao magnetizante/concentracao magnetica/ustulacao salina/lixiviacao em agua quente. Os resultados do trabalho experimental realizado ate o presente concordam qualitativamente com aqueles de outros estudos sobre ustulacao salina/lixiviacao em agua quente de magnetitas titaniferas. E discutida a correlacao existente entre a porcentagem de estracao maxima de vanadio na lixiviacao e as condicoes de ustulacao salina. (autor)Files
