Extração de ferro de esmectita brasileira com emprego do método ditionito-citrato-bicarbonato Iron extraction from Brazilian smectite by dithionite-citrate-bicarbonate method

<abstract language="eng">A natural clay from Campina Grande region (Paraíba, Brazil), with 8.57% of Fe2O3, was used to study the most appropriate condition to carry out the iron extraction, without altering the clay structure in a significant way. Samples were treated with the Dithio...
