Resumo
This laboratory scale investigation addressed two different process routes for the
concentration of a phosphate ore bearing a silicate-carbonate gangue: (i) bulk apatite and
calcite flotation followed by calcite flotation in the presence of phosphoric and citric acids;
(ii) calcite flotation in the presence of carbon dioxide followed by apatite flotation. The
target of selectively separating apatite from the contaminating silicates and carbonates was
achieved. Following the flotation experiments, calcite zeta potential determinations were
performed aiming at clarifying the mechanisms that rule the adsorption of the soybean bran
oil soap onto the mineral surface in the presence of the modifying agents phosphoric acid,
citric acid, and carbon dioxide.
